Hello and welcome to LIVE updates of the Green Group clash between Novak Djokovic and Andrey Rublev. The players are due on court from 1pm GMT.

GAME, SET AND MATCH! - DJOKOVIC 6-3 6-2 RUBLEV. Novak hits back from 15-30 to serve out the match and claim a spot in the last four. He recovered from an early break and never looked in danger with a convincing victory in one hour and eight minutes.

BREAK! - DJOKOVIC 6-3 5-2 RUBLEV. The insurance break is in the bag as a dispirited Rublev again slaps a shot into the net to cough up another service game. Nole will now serve for the match.

DJOKOVIC 6-3 4-2 RUBLEV. No danger there. A wide ace clinches a hold to 15 and Djoker edges ever nearer to a 40th match win at the end of season finals.

DJOKOVIC 6-3 3-2 RUBLEV. Respite. Rublev stays in touch with a fine hold that he seals with a devilish low slice up the line.

DJOKOVIC 6-3 3-1 RUBLEV. Nole consolidates with a ruthlessly efficient love hold and it’s very hard to see a way back for Rublev at this juncture.

BREAK! - DJOKOVIC 6-3 2-1 RUBLEV. Too good! The world No.1 can’t make enough of a 0-30 situation but manages to dig in and force deuce. He’s under the cosh in both corners of his court from there but someone produces that trademark elasticity on the defence to claim a break point with a crosscourt pass. Rublev feels the heat and misses with an attempt down the line to cough up his serve.

DJOKOVIC 6-3 1-1 RUBLEV. Nole has his sights set firmly on that 10th semi final at this tournament. He’s looking sharp and focused out there and eases on to the board with the minimum of fuss.

DJOKOVIC 6-3 0-1 RUBLEV. The forehand does the trick once more as Rublev forces the error into the net to take the game to 30 and open Set 2 on the front foot.

DJOKOVIC 6-3 RUBLEV. Djokovic makes it a formality as he cracks down a wide ace to serve out the opener to love in 36 minutes.

BREAK! - DJOKOVIC 5-3 RUBLEV. The answer is – No! The Russian hooks a backhand wide at 30-30 and Djoker’s eyes light up. He darts in to attack a heavy volley and guides a winning pass beyond his opponent to claim a vital break. He will now serve for the set.

DJOKOVIC 4-3 RUBLEV. The Serbinator dusts himself down after being undone by another forehand howitzer and applies that scoreboard pressure with a hold to 30. Can Rublev keep going toe-to-toe with the 20-time Grand Slam champion at the business end of this set?

DJOKOVIC 3-3 RUBLEV. All square. Rublev’s heavy-hitting in these conditions is making it an intriguing encounter, given that even Nole’s sensational defence is being breached more than he’d like or expect.

DJOKOVIC 3-2 RUBLEV. This time it’s Novak’s turn to feel some discomfort looking to hold serve. Rublev presses at deuce but a devastating, low backhand up the line proves too good and the world No.1 edges ahead once more.

DJOKOVIC 2-2 RUBLEV. Novak knuckles down in search of a back-to-back breaks but can’t convert an opportunity from deuce and Rublev is able to wriggle out of danger. Fair to say, it’s been an intriguing start out there.

DJOKOVIC 2-1 RUBLEV. Djokovic looks to have settled and roars through a much more assured service game to gain the scoreboard advantage.

BREAK! - DJOKOVIC 1-1 RUBLEV. Andrey follows up Nole’s poor service game with one of his own. A double fault gifts the Serb two break back points and although the Russian saves one with a rasping backhand up the line, he then inexplicably drills a drive volley wide when the sanctuary of deuce seemed inevitable.

BREAK! - DJOKOVIC 0-1 RUBLEV. It’s an untidy opener for Djoker yet again. He’s had his troubles kicking off on serve recently and it’s a case of déjà vu here. A rapid crosscourt return from Rublev forces him to fizz long and cough up two break points before he undoes himself with a backhand up the line that flashes just long of the baseline.
