Roger Federer waltzes into the fourth-round, while Kei Nishikori battles through

Roger Federer at the French Open

2009 French Open champion Roger Federer played some fine attacking clay-court tennis to stroll past Norwegian youngster, Casper Ruud in straight sets.

Eurosport pundit and seven-time Grand Slam champion Mats Wilander thought an upset could be on the cards before the match but Federer disproved his opinion in some style.

The 20-time Grand Slam champion took the first set 6-3 and was even better in the second set.

Federer continued to wear down his younger opponent taking the second set 6-1.

A much improved third set from Casper Ruud made it a more competitive contest but ultimately Federer was far too good winning the third set tie-break to triumph 6-3, 6-1, 7-6 (10-8).

The Swiss is yet to drop a set as his fairytale French Open comeback continues.

In contrast, Japan’s Kei Nishikori had to fight very hard to find a way past an inspired Laslo Djere in five sets.

The Japanese star eventually securing a 6-4, 6-7 (6-8), 6-3, 4-6, 8-6 victory and book his place in the fourth-round of the French Open.
