Roger Federer eyes second week after Sam Groth win

Seven-time Wimbledon champion Roger Federer has turned his attention towards the second week of the tournament after booking his place in the fourth round.

The number two seed recovered from a rare blip in the fourth set to beat the big-serving Australian 6-4 6-4 6-7 6-2 on Centre Court.

"I am very happy. It has been a hot week the first week but thankfully I have had easy matches going through without too many long four or five setters. Now we are looking ahead and there are only big matches," Federer told BBC Sport.

Federer will return to action next week when he takes on Spain's Roberto Bautista Agut in the last 16.
