Andy Murray must take time and get fully fit: Federer
Roger Federer has warned Andy Murray not to return to the tour until he is fully fit following his Wimbledon withdrawal.
The two-time champion pulled out on the eve of the tournament after deciding it was too early in his comeback from hip surgery to play best-of-five-set tennis.
Murray made his return to competitive action at Queen's Club last month after 11 months out and also played at Eastbourne.
This is the third time Murray has pulled out of an event just before the start, having also withdrawn from the US Open last summer and the Brisbane International in January.
Federer, who will be 37 in August, said: "I think most important is if he does return, he's fully fit.
"You wonder why did he play Queen's and Eastbourne? Only he and his team know."
Federer began his quest for a record-extending ninth Wimbledon men's singles title with a 79-minute 6-1 6-3 6-4 win over Serbia's Dusan Lajovic on Centre Court yesterday.
