The Hammer striker was hugely influential, but didn't have it all his own way up against Leeds' 19-year-old Premier League debutant Charlie Cresswell.
Here's how the Whites rated, in a game they lost 2-1 having gone ahead through the dangerous Raphinha.
1. Ilan Meslier - 8
Aside from some poor bits distribution and a couple of catches he didn't quite take, he was huge for Leeds. Some massive saves.
2. Jamie Shackleton - 7
Wanted the ball, got on it and was sensible with it, brave too. Defended well, just couldn't make the game-saving tackle.
3. Junior Firpo - 6
Some smart bits of play going forward. Wasn't able to lock down his flank defensively. Unlucky for the goal.
4. Liam Cooper - 7
Defended really very well and had to do a lot of it, second half especially. Distribution wasn't great in the later stages.
5. Charlie Cresswell - 8
Result aside, a debut to be proud of. Not everything he tried came off but he stood up to an extremely tough test. Antonio has got the better of much more experienced defenders.
6. Kalvin Phillips - 6
Better in the first half than the second, when he was unable to get a grip on the game. Ended up fire fighting as Leeds faded.
