  1. Deciding tie-break

    Djokovic 5-7 7-6 (12-10) 6-6 (4-0) Thiem*

    Ah. It's falling apart from Dominic Thiem.

    A forehand goes way long. That could be that already.

  2. Deciding tie-break

    Djokovic 5-7 7-6 (12-10) 6-6 (3-0) Thiem*

    The Djokovic serve isn't missing at the moment.

    He has a big early advantage.

  3. Deciding tie-break

    *Djokovic 5-7 7-6 (12-10) 6-6 (2-0) Thiem

    A big serve from Djokovic.

  4. Deciding tie-break

    *Djokovic 5-7 7-6 (12-10) 6-6 (1-0) Thiem

    Oh no. A double fault from Dominic Thiem to start the breaker.

    Remember Thiem had four match points in the second set tie-breaker.

  5. Djokovic forces deciding tie-break

    Djokovic 5-7 7-6 (12-10) 6-6 (0-0) Thiem*

    It's tie-break time ladies and gents.

  6. *Djokovic 5-7 7-6 (12-10) 5-6 Thiem

    A Djokovic ace. 30-15.

    It's high quality stuff.

  7. *Djokovic 5-7 7-6 (12-10) 5-6 Thiem

    Stunning winner from Thiem. That backhand is sensational.

    15-15.

  8. Djokovic serving to stay in the match

    *Djokovic 5-7 7-6 (12-10) 5-6 Thiem

    So will it be a deciding tie-break or can Thiem seal the deal here?

    Djokovic finds the outside of the line with a crunched forehand. Not bad, that. 15-0.

  9. Thiem holds

    *Djokovic 5-7 7-6 (12-10) 5-6 Thiem

    This won't help Djokovic's mood as he puts another ball wide. Thiem does what he has to do and holds with the Serb breathing down his neck.

    Now, can he muster something in Djokovic's service game?

  10. Andrew Castle
    BBC Sport tennis commentator at the O2 Arena

    Wow. Vesuvius. Seems like it's been bottled up for a while.

  11. Djokovic 5-7 7-6 (12-10) 5-5 Thiem*

    A huge roar from Djokovic after missing a return! That has been coming for about two hours.

    I think they heard that in SW19.

    40-30.

  12. Djokovic 5-7 7-6 (12-10) 5-5 Thiem*

    This is tense now. Any mistake will likely be costly.

    Thiem puts a forehand into the net, meaning we're at 30-30.

  13. Djokovic holds

    Djokovic 5-7 7-6 (12-10) 5-5 Thiem*

    Djokovic levels up with an emphatic forehand winner. Who are you backing from here?

  14. *Djokovic 5-7 7-6 (12-10) 4-5 Thiem

    Thiem holds up a hand to apologise after a lucky net cord wins him the second point. Secretly, he's loving that inside.

  15. *Djokovic 5-7 7-6 (12-10) 4-5 Thiem

    Novak Djokovic serving to stay in this semi-final...

    He begins with a forehand winner behind a powerful first serve.

  16. Andrew Castle
    BBC Sport tennis commentator at the O2 Arena

    If there is one change from Dominic Thiem all this year, it's that match-playing ability and that belief of knowing what to do at the right time and doing it.

  17. Thiem holds

    *Djokovic 5-7 7-6 (12-10) 4-5 Thiem

    Ctrl C + Ctrl V.

    Dominic Thiem doesn't flinch under pressure with the big serve helping him through.

  18. Djokovic 5-7 7-6 (12-10) 4-4 Thiem*

    It's Domi Thiem's turn to applaud his opponent now after being given the run around by his opponent. There were more slices in that point than an episode of the Bake Off.

    30-30. Djokovic has a sniff.

  19. Djokovic holds

    Djokovic 5-7 7-6 (12-10) 4-4 Thiem*

    Danger averted by Novak Djokovic. He's been through moments like these plenty of times before.

  20. *Djokovic 5-7 7-6 (12-10) 3-4 Thiem

    Despite an error, Thiem still has a sniff after getting to deuce.
