Novak Djokovic might soon want to replace his white shoes with the green `23` printed on the heel. Reason? The seven-time Wimbledon champion has won 23 Grand Slam singles titles, and he could add to that total on Sunday if he wins three more matches at the All England Club.

"Well, obviously if it happens in less than a week`s time that I reach the 24, then we`ll have to use the 24, I guess," Djokovic said. "It`s not going to be a big problem to do that."
