Roger Federer will be unstoppable in today's Wimbledon final if he serves as well as he did in his semi-final win over Andy Murray, according to former British player John Lloyd.

The Swiss is bidding to win his eighth title at the All England Club when he faces Novak Djokovic, and his serving has been a key component of his game so far.

In the last four, Federer hit 20 aces and had a first-serve ratio of 76% on his way to a straight-sets win.

Lloyd wrote in the Daily Mail: "If Federer continues to maintain a first-serve percentage of 76% and hits the spots, then he beats Djokovic. Federer has only lost once when he is at 76% or higher on his first serve.

"In that case, Djokovic is not going to break him, so the only way for the Serb to have a chance would be to win sets in tie-breaks. I see nothing from Djokovic's return that tells me he is better than Murray in that department on grass."

Federer lost to Djokovic in the final last year.
