1. Omar Marmoush and Savinho's races are run as Rayan Ait-Nouri and Claudio Echeverri come on for the final 10 minutes.
2. Oh, Liam Delap...
A fantastic ball from Nicolas Jackson and he plays Delap through on goal.
He hits the ball into the ground and it goes wide. That was a poor miss.
3. The Blues are now on top. They will not want half-time to come.
Johor Darul Ta'zim have lost their momentum.
4. Tosin Adarabioyo has been busy, he takes on a shot from 30 yards out, but it was always rising.
5. The ball drops to Reggie Watson in the box.
Watson fires it into row Z...
6. Three minutes added on.
7. Rico Lewis finds the run of Divin Mubama to put him through on goal.
You never really felt confident he'd find the back of the net as Salvi Esquivel makes the save.
8. Jamie Gittens has been poor in defence, but he has some fast feet and he manages to win a free-kick. And for some reason, Liam Delap clashes with Eddy Israfilov.
The referee gives Delap a yellow card.
9. One of the commentators has no idea who Lee Kang-in.
Didn't seem to know he's a two-time Champions League winner with PSG and that he's very talented.
Every day's a school day, I guess.
10. Oscar Arribas has a shot from the edge of the box, but it is a comfortable save for Teddy Sharman-Lowe.
11. Atleti work the ball really well into the box. It's squared for Lee Kang-in to put his laces through but he can't quite keep it down.
This place would've erupted if he'd scored.
12. 
Well taken by Liam Delap.
He fires it into the top corner with real venom.
Wins the penalty and scores the goal. That's exactly what Delap needed.
13. There's no Bruno Guimaraes for Arsenal today, but here are his best Premier League moments after the Gunners confirmed the Brazil midfielder from Newcastle on Saturday.

14. Liam Delap finally comes alive in the box and he gets the better of Kevin Medina.
Medina has his arm around Delap's chest and he also catches the forward on the heel.
A clear penalty.
15. Oscar Arribas causing problems.
He runs direct towards the Chelsea backline, but he plays the wrong pass to Shahab Zahedi.
Zahedi is also stood in an offside position. Poor from Arribas - he could have punished Chelsea.
16. Atleti suddenly look a lot sharper than they did.
That's probably what making 10 changes does to a side.
17. Reggie Watson pings a long ball to Liam Delap.
However, it is dealt with by Kevin Medina.
Delap looks frustrated....
18. Back playing in Seoul.
The players have been fed and watered.
19. Johor Darul Ta'zim are well connected out of possession.
Soon as Chelsea get on the ball, the Malaysian side drops into their shape swiftly.
Chelsea are struggling to find the space - Liam Delap and Nicolas Jackson, who started strongly have now gone quiet.
20. Chelsea continue to pass it around at the back.
Johor Darul Ta'zim are just waiting for the Blues to make a mistake.
