Hello and welcome to our continued coverage of day 10 of the Australian Open, with world number one Novak Djokovic playing fifth seed David Ferrer for a place in the semi-finals.

DJOKOVIC 6-4 7-6(4) 6-1 - GAME, SET & MATCH - A big serve gives Ferrer problems and brings up two match points for Novak. He aces and that's it! All over! It's the top four into the semi-finals, with Djokovic to play Andy Murray!

DJOKOVIC 6-4 7-6(4) 5-1 - BREAK - Djoko whips a forehand down the line but when he loses the next point, he 'does a Murray' and reaches for his leg. Ferrer challenges a line call on the next point - successfully - but the replayed point goes Nole's way. The Spaniard hits back with a forehand winner that we haven't seen for a while to prompt applause from Djokovic but it's the Serb who deserves the acclaim two points later as he hammers a forehand winner to break once again!

DJOKOVIC 6-4 7-6(4) 4-1 - Some huge hitting from Nole takes him to 40-15 before he seals another hold with a delightful lob which Ferrer, standing at five-foot-nine, flails at in vain. Nole's overcome whatever was ailing him earlier, and he's closing in on a date with Andy Murray, but it's harsh on Ferrer at the moment. The Spaniard's efforts deserve more than what he has reaped so far.

DJOKOVIC 6-4 7-6(4) 3-1 - Ferrer holds as Novak hits a couple of wayward potential winners. In fact the penultimate one could well have been a knockout blow to Ferrer had it landed a few centimetres the other way. As it is, this one's still alive. Ish.

DJOKOVIC 6-4 7-6(4) 3-0 - Ferrer looks despondent as Nole races to a 40-0 lead and when he hits his next return of serve out at the baseline, the world number one opens up a three-game lead in the third set. That second set tie-breaker already looks like it was the true decider of this match.

DJOKOVIC 6-4 7-6(4) 2-0 - BREAK - Djokovic has stepped up his game here. He fires his 14th forehand winner of the night to take a 30-15 lead. He then brings up two break points by simply wearing Ferrer down. A shank wastes the first one but he unleashes a forehand right into the corner that Ferrer can't return! Break!

DJOKOVIC 6-4 7-6(4) 1-0 - Injured/ill/unable to breathe or not, Djokovic is still two sets up and it's going to take a truly amazing comeback from Ferrer to turn this around. Nole powers through the first game of the third set, serving out to love, as if to reinforce the point.

DJOKOVIC 6-4 7-6(4) 0-0 - This is amazing stuff on Rod Laver Arena! Djokovic, even though he seems ill or carrying an injury, is still two sets to the good and just one away from the semi-finals. The latest is that maybe he's struggling with his breathing. The big winner at the moment is Andy Murray, who awaits the winner.

DJOKOVIC 6-4 7-6(4) - SET - Djokovic shanks one to drop to 0-2 before Ferrer makes it 3-1 with a lovely drop volley. He ruins his hard work though when he fires a wild forehand wide and we're back on serve at 3-2. Ferrer makes it 4-2 as Nole goes long at the baseline but the Serb fights back to level at 4-4 after an incredible rally! Ferrer then hits the net on a regulation forehand before Djokovic brings up set point with a monster forehand down the line! He gets it! Ferrer goes long!

DJOKOVIC 6-4 6-6 - TIE-BREAK - Djokovic advances to the net but he can only manage to hit the tape and when the net comes into play again a point later - on a lucky net cord that Ferrer benefits from - Djokovic is facing break point. Ferrer wins it! And we're going to a tie-break.

DJOKOVIC 6-4 6-5 - BREAK - Djokovic fires a forehand winner down the line to take a 30-0 lead and even though he loses the next two points, he brings up break point with a forehand winner down the line. He goes on to take it! Amazing! Maybe his problem isn't a hamstring at all. A stomach issue maybe? Maybe that's why he was on his haunches when we first noticed it.

DJOKOVIC 6-4 5-5 - This is exactly the tonic Djokovic needs at this stage. He challenges a service call - he's proved correct - on the first point and he goes on to win the replayed point. He ends up holding to love and now if he can eke out a break now, it would be a huge boost.

DJOKOVIC 6-4 4-5 - Ferrer booms down an ace to seal another held service game but Djokovic seemed to be moving a little more freely during that game. Has he shaken it off? Honestly, who knows? It's certainly intriguing.

DJOKOVIC 6-4 4-4 - Nole holds serve and hangs in there. He's just a break and a hold away from a two-set lead but still there are real concerns over his fitness. Djokovic lost here in the quarter-finals as defending champion in 2009 (to Andy Roddick) and again in 2010 (to Jo-Wilfried Tsonga).

DJOKOVIC 6-4 3-4 - Some wayward shotmaking from Nole gifts this game to Ferrer. It's difficult to know exactly what's going on with Djokovic at the moment because he's yet to call the trainer. Yet he's not moving freely in between points. It could be a slight tear of his hamstring but, of course, that's pure speculation.

DJOKOVIC 6-4 3-3 - Djokovic opts not to call for a trainer at the changeover and it looks like he'll soldier on. It's a mystery why he's taken that view as he's clearly got a problem. Again Ferrer punishes him to bring up break point - but some incredible defensive work from Djoko saves it! And he goes on to hold with a forehand winner sealing it, but surely such a physical battle will take its toll sooner or later on the Serb, who hasn't shaken off his problem.

Jamie Murray: "Ferrer has a great chance to win this match in this moment. Looks stronger out there physically and mentally. Djoko visibly out of sorts."

DJOKOVIC 6-4 2-3 - Djokovic seems to be in some discomfort, and he's limping in between points. Ferrer looks to take full advantage as he aces on his way to holding serve and taking the lead in this second set! Wouldn't be surprised now if Nole called on the trainer.

DJOKOVIC 6-4 2-2 - BREAK - Novak makes a rare sortie towards the net, where he makes winning the point look easy. Ferrer counters with the same tactic to level at 30-30, making a nice change to what we have seen so far this match. And the Spaniard uses that momentum to go on and break for the first time! But the real drama comes as Djokovic stretches to reach the final ball. He seems to pull something and could be in trouble! He hangs his head for a moment... is he injured?
