And that’s the end of an enthralling 45 minutes of football.
Chelsea started superbly and were utterly dominant after going ahead through Felix and also having goals disallowed from the Portuguese star and Havertz.
Out of nowhere, West Ham created a couple of chances and scored imminently, through former Blues man Emerson.
It’s been pretty even since then but both teams look vulnerable defensively.
Felix has been particularly brilliant during the first period but it’s all to play for in the second 45.
The first half is winding down as both teams exchange spells of possession.
Coufal has put in a couple of hefty and late challenges which have gone unpunished by Craig Pawson.
Four minutes added on.
Good play from Chelsea and Madueke cuts in on his left foot and forces Fabianski into a good save as he sprawls away to his right.
The former PSV winger was slightly culpable for Emerson’s goal along with James but he’s looked good going forward.
Benrahma is then bearing down on goal at the other end after a Silva mistake but the Brazilian puts in a superb block.
Chelsea then break and have four-on-three but Mudryk plays a poor pass and West Ham clear.
This is a proper game.
We said it had been better from West Ham.
Coufal puts a good ball into the box, Bowen flicks it on and former Chelsea player Emerson is at the back post and finishes superbly.
1-1 and game on!
