Hello and welcome to live updates of the French Open quarter final encounter between world number one, Novak Djokovic and seventh seed, Tomas Berdych.

DJOKOVIC 5-3 BERDYCH. The Serbinator fires a delightful pass down the line after Berdych got to a cunning dropshot to consolidate to 15. The world number one is playing some top tennis at present and is one away from taking the opener.

BREAK! - DJOKOVIC 4-3 BERDYCH. The world number one has indeed stepped it up. Some vintage returning including a crosscourt winner to seal the deal to 15 sees him leave Tomas with what is a very familiar feeling when these two lock horns.

DJOKOVIC 3-3 BERDYCH. Novak shifts his service game up a gear, breezing to a perfect game.

DJOKOVIC 2-3 BERDYCH. Another accomplished hold from Berdych. His win over Ferrer in the previous round has given him confidence and he'll be feeling pretty good about this start.

DJOKOVIC 2-2 BERDYCH. Tomas going for his shots but despite being in the game at 30-15 he fires into the right-hand alley and then long of the baseline to allow Nole an easy hold.

DJOKOVIC 1-2 BERDYCH. The Birdman is feeling his way into this. He hasn't given Djokovic too many opportunities to turn up the heat and keeps his scoreboard advantage with a game to 15.

DJOKOVIC 1-1 BERDYCH. Novak doesn't waste much time getting on the board. He knows he has a psychological edge over Berdych from their head-to-head record and will want to exploit that with some early blows.

DJOKOVIC 0-1 BERDYCH. Tomas roars into a 40-0 lead with some big serving but gets a little nervy as Djoker pulls two back. Patience in a lengthy rally gets him over the line for the hold as Djokovic fizzes just long of the baseline.

The players are about to complete the warm up. Berdych will get us underway by serving first.

HEAD-TO-HEAD: Djoker is on a 10-match winning streak against the Birdman and owns the head-to-head 23-2.
