Maria Sharapova and Grigor Dimitrov confirm break-up

The break-up was confirmed by 24-year-old Dimitrov to Bulgarian media, and it came as little surprise after the pair had been photographed holidaying separately after Wimbledon.

"Our paths split," said Dimitrov, currently number 16 in the ATP rankings.

"We experienced wonderful moments together. I wish her much happiness and success in life and in tennis.

"Now I'm concentrated entirely on the game and I'm sure the results will soon be seen... This is the summer of the new beginning for me."

Dimitrov, who climbed to number eight in the world last year after reaching the Wimbledon semi-finals, has had a lean year and is still to reach a final.

Sharapova, 28, announced that her and Dimitrov were a couple in May 2013.
