When Roger Federer steps out on court today he will no doubt be feeling the weight of expectation on his shoulders.

But there is one man who may just have had more sleepless nights than the former champion over the last fortnight, a life-long fan who has put a £50,000 stake on Federer gaining his eighth Wimbledon title.

George, 36, will be holding his breath this afternoon as the Swiss number five attempts to beat Marin Cillic to become the oldest Wimbledon champion since the beginning of the open era in 1968.

And to add to his nerves as he waits to see if Federer can pull off another Wimbledon title and at the same time land George a handsome payout is the fact he has not told his girlfriend about the bet.
