Tottenham Hotspur striker Harry Kane has said that the side's recent struggles marks the "toughest" period in his time at the club.

Spurs escaped with a late draw at home to Premier League strugglers Watford on Saturday, following a controversial Dele Alli equaliser.

Boss Mauricio Pochettino has come under pressure following a poor start to the Premier League season that has seen just three wins, including losses to Brighton, Leicester and Newcastle.

"It's hard to put a finger on exactly what's wrong," Kane said at a news conference on Monday. "Sometimes when you're having a run of form like this, things don't always go your way in games. It's about sticking together and if we win tomorrow night that can kick start us.

"It's probably the toughest time since I've been here. It's just another challenge though. The road to success will always have bumps and this is just one of them."

Pochettino maintained that his side are just low on confidence, saying: "For many of our players this is the first time they've been in a tough period.

"For 99 per cent of our players they were in a very good period in the past five years, it's a very new thing for them."

"It's natural that when suffer a defeat like we suffered [7-2 loss to Bayern Munich]. When it should have been 3-1 to us in the first half and then we conceded like we did in the second half that is tough. It affects your confidence and trust.

"Then Brighton came so quick and it's normal that we're in a period where we're fragile."

Spurs, who reached the final of the Champions League last season, will look to end their poor form in the competition this season when they face Serbian champions Red Star Belgrade at the Tottenham Hotspur stadium on Tuesday.
