Novak Djokovic takes on Grigor Dimitrov tonight in the second round of the 2013 Mutua Madrid Open (19:00 BST start).
Djokovic has a tall order ahead of him in his first match at this year's Madrid Masters. Rising star Dimitrov has been particularly impressive of late, showing plenty of top ten potential. The fact that he nearly managed to beat Rafael Nadal in Monte-Carlo last month backs this up.
"He's very talented player," Djokovic said ahead of his Madrid opener.
"He has capacity to play in a very, very high level because he's very talented; he's an all-round player, and he showed it.
"With his style of the game you think that he can play his best on the hard courts and the faster courts, but he showed in Monte-Carlo when he pushed Nadal to three sets he can play equally well on clay.
"There is an altitude here, 500, 600 metres, which helps the servers and more aggressive players. The ball travels through the air faster, so that can make Dimitrov very dangerous on this surface. I absolutely want to not underestimate my opponent. I will just try in this next few days to get as much time on court as I can in order to get ready."
Dimitrov made it through to the second round on Monday night with a 6-2 6-4 win over Spain's Javier Marti. Marti, who like Dimitrov has a one-handed backhand, put up a good fight but couldn't quite take down the rapidly improving Bulgarian.
This win should have helped Dimitrov to adjust to the red clay, but Djokovic's last match on the dirt was a straight sets victory over Nadal in the Monte-Carlo final. After a result like that, Nole's place in the last sixteen doesn't appear to be in doubt.
Prediction: Djokovic in two.
