BORIS PRIMED FOR BIG CLASH

ROGER FEDERER and Rafael Nadal will have every tennis player on earth glued to their Wimbledon showdown today.

That is the view of threetime champion Boris Becker, who says the first meeting between the pair at the All England Club in 11 years is pure box office.

Federer and Nadal haven’t clashed at Wimbledon since Nadal won an epic, rain-hit final in 2008 (right) that lasted almost seven hours.

Becker said: “I think it’s the one match where every tennis player alive is going to tune in.

“Two ultimate warriors. One with 20 majors, the other 18. Everybody remembers 2008. The other semi is as important but the history in the making is what we want to see.”

In that other semifinal, Novak Djokovic faces Roberto Bautista Agut, whose run has forced him to cancel his stag do in Ibiza.
