Five-time Wimbledon champion Bjorn Borg says no player outside of the top four seeds—which are Rafael Nadal, Novak Djokovic, Roger Federer and Andy Murray—has a realistic chance to win Wimbledon.

"People always talk about one or two great players, and now we’ve got four," Borg told the Daily Telegraph. "I cannot see anyone winning Wimbledon apart from those four guys. There’s such a big gap between the top four and everyone else, They have been playing so well over the last few months, so consistently. Looking over the years, you had two rivalries, or maybe three, but now you have four guys. I don’t know how long you would have to go back for four great guys but probably a long, long time. This is great for tennis."

Borg gives Murray a chance to win the title, even though the world No. 4 has never reached the final, but sides with Federer, who has won six titles.

"After having the best clay-court season he’s ever had, [Murray] played great tennis at Queen’s, so he is playing with a lot of confidence and he feels happy with himself," said Borg. "Just a couple of months ago, when he went to Monte Carlo, he was playing poorly, he had no confidence and nothing was working. Now I think he is right up there, both physically and mentally, with the others. This is a tough time to be trying to win Slams, but he’s beaten these guys, so he knows when he walks on court that he can beat them again. He’s never been as ready to win Wimbledon as he is now...[But] I would go for Federer because of the way he played in Paris. That was his best tennis ever at the French Open. From the first match to the last, it was unbelievable to see. And he prefers the grass to the clay."
