Novak Djokovic has admitted his relief at making it through at the Monte Carlo Masters with a three-set victory over Mikhail Youzhny in the second round.

The world number one, who has recently been suffering with an ankle injury, lost the first set but came back to see off his Russian opponent 4-6 6-1 6-4 on Wednesday.

"Today was a big test," Sky Sports News quotes Djokovic as saying. "I had a great quality opponent.

"I'm very happy to win, I'm just happy to compete, to be honest. I didn't know if I'm going to be playing the tournament up to yesterday (Tuesday) basically."

Djokovic will take on 14th seed Juan Monaco in the next round with a quarter-final spot awaiting the winner.
