Roger Federer and Rafael Nadal reached the fourth round at Wimbledon with straight-set victories over French opponents.

Spanish world number two Nadal - a two-time winner at SW19 - defeated Jo-Wilfried Tsonga 6-2 6-3 6-2.

Eight-time Wimbledon champion Federer beat Lucas Pouille 7-5 6-2 7-6 (7-4).

Nadal will play Britain's Dan Evans or Portugal's Joao Sousa in the next round while Federer will take on Italy's Matteo Berrettini.

It was the first time Nadal had played Tsonga at the All England Club and their first meeting since 2015.

"I'm very happy. I think I played a great match," Nadal told BBC Sport.

"I was returning well, playing aggressively with the forehand and the backhand. I think I did a lot of things well.

"Tsonga is someone you don't want to face in the third round at Wimbledon.

"Every single day is a battle here. It is not a surface I play a lot of matches on during the year."

Victory over Pouille saw Federer become the first player to achieve 350 Grand Slam singles match wins.

"It was tough. It was a hard-fought match, especially in the first set," Federer said.

"I think going up two sets was key. The third was tough, it was very even.

"There is always a relief winning a third-set breaker because if it goes the wrong way, you might be here for a few more hours."

Nadal in stylish victory

In his first meeting with Frenchman Tsonga at a Grand Slam in 11 years, Nadal secured an early break to move 4-1 ahead and made just three unforced errors throughout the opening set.

The second set stayed with serve until Nadal broke to lead 4-2, and he almost sealed the set on a break before Tsonga fought back to force him to serve out for a 2-0 advantage.

Nadal dominated the third set, gaining a double break, and he almost broke Tsonga yet again on his third match point but the two-time Wimbledon semi-finalist was able to hold.

However, Nadal quickly served out the match to love in one hour 48 minutes, with Tsonga seemingly nursing a hand injury after a tumble earlier in the game.

Federer made to sweat by Pouille

Federer was meeting Pouille for the first time at a Grand Slam and the first set proved a cagey affair, staying on serve with the Frenchman scuppering two break points.

But it was Federer who finally broke serve and he did it at the perfect time, sealing the opening set on his second set point.

The second set proved the polar opposite, however, with Federer sealing a double break early on to go 4-0 up before failing to hold his own serve.

Just as he did in the opener, he won the set on a break to move just one away from a place in the fourth round.

Little could separate the two in the third set with Federer missing match point as Pouille held to take the set to a tie-break, which Federer won.

Elsewhere, eighth seed Kei Nishikori beat American Steve Johnson 6-4 6-3 6-2.

Tennys Sandgren defeated Fabio Fognini 6-3 7-6 (14-12) 6-3 and will play American compatriot Sam Querrey next after he beat John Millman in straight sets.
