Good evening and welcome to Eurosport's LIVE coverage of the Premier League clash between Chelsea and West Ham. We'll bring you all the goals and action as it happens at Stamford Bridge. Kick-off: 20:00.

It's an opening day win for Conte as Chelsea manager, but he was made to sweat for it! West Ham looked to have salvaged a point for themselves, but Costa had the final say. There were glimpses of what the Italian wants from the Blues, but they will have to improve as the season goes on.

FULL-TIME: Chelsea 2-1 West Ham

COSTA WANTS A PENALTY! The Brazilian-born striker goes down in the box but the referee decides that he was looking for it and the replays show that there wasn't much contact.

Costa arguably shouldn't even be on the pitch! There will be those who claim he should have seen a second booking for that tackle on Adrian. But he might have had the final say.

Four minutes of stoppage time to be played at the end of the second half.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Chelsea 2 (89 mins - Diego Costa) West Ham 1. That could be the winner! Costa picks up the ball 20 yards out, turns and strikes a low finish into the low corner of the West Ham net. Collins couldn't get out quick enough!

COULDN'T MAKE A CONNECTION! Hazard takes control of the play and whips a cross into Costa, but the Chelsea striker couldn't strain enough to make a connection at the back post.

On comes Batshuayi for his Chelsea debut. The Belgian striker will play up front alongside Costa as part of a front two. The Blues need a goal from their new signing! No pressure.

Chelsea change: Oscar OFF, Michy Batshuayi ON.

Nervous moment for Kante! The French midfielder brings down Payet in the centre circle. Remember, he's already on a booking. Should he have seen a second yellow card?

It took a while for this match to come to the boil, but we have a proper derby on our hands now. Both teams are attacking whenever they get the ball. They want a winner from this!

That equaliser demonstrates the danger of not taking your chances when you are on top. Chelsea really should have been out of sight. Instead, they have been pegged back.

Chelsea change: Willian OFF, Pedro ON.

Payet is starting to have a real impact on this match now. West Ham are pressing forward not that they have the goal. They're not sitting back and the Frenchman is pulling the strings.

They haven't looked like scoring all night and yet West Ham are now level! What a strike it was from Collins. A striker would have been proud of that one, never mind a defender!

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Chelsea 1 West Ham 1 (76 mins - James Collins). West Ham have an equaliser! A corner kick to the back post causes mayhem in the Chelsea penalty area and Collins hammers home a half volley. They're level!

PAYET FREEKICK DEFLECTED WIDE! The Frenchman couldn't get his freekick up and over the wall, with the Chelsea wall deflecting his shot wide of Courtois' goal. Chelsea fans exhale.
