After winning four of their first five matches of this IPL season, Kolkata Knight Riders have lost their last six matches on the bounce. Their batting has come under plenty of criticism for the situation they find themselves in, but Andre Russell believes the blame lies elsewhere.

"We have a good team," Russell said on the eve of Knight Riders' match against Mumbai Indians. "But having a good team and making bad decisions, I think you will always lose games. And that's what we've been doing.

"I could pinpoint a few games where if we'd just looked to bowl tighter, and bowl bowlers who would restrict the game - the right bowlers at the right time [the results would've been different]. They say our batting has been struggling, but our batting hasn't been struggling really. We get the totals that we should defend, and we should restrict teams to lesser totals and go in and get those runs. And we don't really take our catches, we've been the worst fielding team so far. It's plain on TV, everyone's seeing it."

Russell has been Knight Riders' standout performer this season - with 406 runs at a strike rate of nearly 210, and eight wickets - but he says his team's performances have left him deflated.

"To be in this position is not the most healthiest," Russell said. "I find myself just being in my room for the last couple of days. Losing game after game… I'm not the type of guy to go walking around like I'm doing something good. Even if I score a half-century or get five wickets and we come out on the losing end, it doesn't make me want to leave my room.

"We as cricketers, we have to hold our passion inside and not show it on the television. I'm passionate inside. Sometimes it may show on the field. I may get upset at a team-mate for dropping a catch or not taking a half-chance. Because when we mess up, [opposition] guys take our half-chances. It's hard to go walking around, losing six games in a row. It's not healthy. I'm feeling down at the moment, but tomorrow when I cross that rope, my level will be 150."

As for his highly-debated batting position - he has himself advocated going higher up the order - Russell hinted at more flexibility in the matches to come.

"Yes, there have been conversations with the coach, and he's backing me to go in whenever the team needs me," Russell said. "Maybe tomorrow you'll see me a bit earlier, maybe I'll be coming in at the same lower-order spot. It all depends on what happens tomorrow. You can't predict the future.

"If we should get a good start, then maybe I'll just stay where I normally bat. I can go in at four-five overs to go, I'm happy doing that. If the team needs me to bat 12 overs tomorrow, I'm happy to bat 12. If they need me to bat three or four, that's my job."

Asked about the prospect of facing one of the best attacks in the IPL in Mumbai Indians, Russell said the pressure would be on the bowlers and not on him.

"I never fear any bowler. Never. Bowlers fear me! (laughter) I'm not bragging or anything," Russell said. "I can get out in one ball tomorrow, or the first ball they bowl can go for six. I'm not afraid to get out. It's not a life and death situation. You're giving yourself a chance to score runs, and they're trying to get you out.

"[Jasprit] Bumrah is a top bowler, [Lasith] Malinga - top bowler. But they're human beings. Tomorrow they can bowl a few balls that slip out of the fingers and don't come out like they normally come out - and I'm in business. I never back down."

The Eden Gardens crowd has witnessed four straight Knight Riders defeats. Russell was amazed that spectators were still packing the stands.

"It's been unbelievable to be honest. We keep losing game after game, but the stadium is always full," Russell said. "And I know Sunday we'll get another full crowd. It's just amazing.

"In the Caribbean, if I was playing for West Indies or Jamaica, and we lose six games in a row, you'll not see no fans to be honest. You're going to see a few die-hard fans, but you won't see the stadium full like this. People are going to say, 'you're not playing good cricket'. It's not like the English Premier League where guys look to fight. It's just amazing. I would appreciate if the stadium gets full tomorrow. That would really get me pumped, after hitting a boundary and taking a wicket to hear a big cheer. That would really keep us going."

Pakistan legspinner Shadab Khan has been given a two-week course of medication by doctors in England, along with a prescription of complete rest, in an attempt to cure the virus that ruled him out of their forthcoming series. He will now return home from London and undergo another round of blood tests in Lahore next month to determine his fitness for the World Cup.

Shadab was originally named in both squads for the England series and World Cup only to be ruled out two days after the announcement after failing a blood test. He was subsequently replaced with fellow legspinner Yasir Shah, while the PCB arranged an appointment with a London-based gastroenterology and hepatology specialist.

The possibility of being without Shadab, a key player over the last two years, would be major dent ahead of the World Cup, although the PCB is optimistic that he may still recover in time. The PCB can make changes to the squad without seeking ICC permission until May 23. After that date and through the tournament, the ICC's technical committee will process any replacement requests.

Shadab was the only frontline spinner named in Pakistan's original 17-man squad to tour England, however, the presence of Mohammad Hafeez, back after a thumb injury, and Imad Wasim gives them options in the spin department for a one-off T20I and a five-match ODI series between May 5 and 19.

Pakistan also have Mohammad Amir pushing for a World Cup spot, having been named alongside Asif Ali as the two men outside the World Cup 15. Amir's form over the past 18 months hasn't been good enough to win selection in the preliminary squad but he has the chance to push his case in familiar conditions - the country where his last ODI high point occurred in the final of the 2017 Champions Trophy.

West Ham have delivered a blow to Tottenham's top four hopes, as Michail Antonio's second half strike gave them a 1-0 victory -- the first goal scored by a visiting team at the new stadium.

This was the fifth match in all competitions for Mauricio Pochettino's men at the Tottenham Hotspur Stadium and they had won the previous four without conceding a goal, but that run was ended after 67 minutes in this London derby in superb fashion.

Marko Arnautovic found Antonio with a fantastic ball over the top of the Spurs defence and the Englishman controlled the ball with his chest before firing past Hugo Lloris.

Tottenham, who are still without injury top goal-scorer Harry Kane, started the match with Son Heung-Min in attack as Fernando Llorente was on the bench -- while defender Jan Vertonghen was a surprise absentee.

The first 45 minutes saw few chances with West Ham's Felipe Anderson producing an impressive, surging run before shooting tamely straight at Lloris. Tottenham saw more of the ball but West Ham goalkeeper Lukasz Fabianski did not have a save to make in the opening half.

Son had a penalty shout turned down early in the second half, while Christian Eriksen hit a free-kick from a good area straight into the wall before Antonio opened the scoring.

Tottenham came close to equalising with the last kick of the game when substitute Vincent Janssen saw a header cleared off the line, but West Ham held on to secure a huge victory.

"For us to come here and get the first win is a great achievement," Antonio told Sky Sports. "The fans are loving it and we've just got to keep it going."

Pochettino was dismayed by the result but urged his side to pick themselves up quickly for Tuesday's game.

"I think the first half was good for us, second half they were better," he told a news conference. "They had more energy.

"We conceded a lot of space to run... We lost a lot of ball we gave them the possibility to make the game.

"I'm disappointed; it's a setback. We wanted the three points, we wanted to arrive at the Champions League game in a good way but it was not (to be) but now we need to move on. It's about the recovery and get ready for Tuesday to play."

The defeat may not be too damaging for Spurs, as they remain three points clear of fourth-place Chelsea, who face sixth-place Manchester United on Sunday. West Ham, meanwhile, remain 11th.
