7:11 CET - Daniil Medvedev (27) will head into the Monte Carlo Masters hoping to strike the right balance as the world number four looks to tweak his game for the claycourt swing without compromising on the style that has delivered four titles in 2023.
Medvedev has won 18 of his 19 titles, including the 2021 US Open, on hardcourts, the only exception coming at the Mallorca Open when he triumphed on grass the same year.
He has been in red-hot form this season having triumphed in Rotterdam, Doha, Dubai and Miami but the 27-year-old knows clay presents a different challenge for his game.
"I definitely have to change my game because my strokes are too flat and clay doesn't let the ball go through the court as much," Medvedev, who plays Lorenzo Sonego or Ugo Humbert first in the ATP 1000 tournament, said.

7:06 CET - Novak Djokovic (35) said he hopes to hit the ground running at Monte Carlo having begun preparations for the clay season early after the world number one was forced to skip tournaments in the United States last month.

The Australian Open champion last competed in early March when he lost in the Dubai semi-finals and said his enforced absence from the Tour helped him focus on Monte Carlo, where he lost in the second round last year.
"I've done more training on clay, which is positive if you think about the clay season," said Djokovic, the 2013 and 2015 champion who meets Mackenzie McDonald or a qualifier first.
