Nothing he could do about the opening goal which was hit early and with great pace, although he did get his fingers to it. Delph poked the ball into his own net and similarly, he could do little about it. Fumbled a shot from distance but the rain made it difficult.
Made his home debut in a game that didn't reflect well on defenders. Beaten by Amalfitano on his left and could have given a penalty away had Clattenburg deemed it worthy, but was lucky with the decision.
Brought back into the side at right-back and found both opening goals from the Baggies come down his flank, failing to stop the cross into the box for the second as they piled forward in numbers. Hit a dangerous cross for Bacuna's leveller but taken off in the second half.
He didn't get the right side of Mulumbu for his goal where the defence had eyes on the ball instead of tracking the run of the Baggies midfielder.
Found himself up against a forward matched for strength in Anichebe and had his work cut out. Lost a number of battles with him, also letting Mulumbu slip free for his goal. Looked stronger when Anichebe was taken off and led near the end.

Put himself about and covered a lot of ground but the quality wasn't always there on the ball. Didn't look strong enough and that's his main weakness, especially given his lack of pace. Later replaced by Sylla as the game drew to its conclusion.
He was unlucky to see his out-stretched foot divert the ball into the net for the Baggies' second goal but then made up for it at the other end with a fantastic strike. He jinked away from Reid and hammered the ball off the bar and in.
Looked sloppy in midfield, losing possession of the ball too easily and running into trouble with the ball at his feet. Didn't seem to be on the same wavelength as other players around him and was slow to react to passes.
Pushed further forward in the absence of Gabby Agbonlahor and looked lively going forward, putting himself in the right positions and scoring a dramatic equaliser - clumsily, albeit. Worked hard for his side and was a threat going forward.
Pounced on a ball over the top and looped his effort on goal up and over the keeper to give his side a much-needed boost minutes after going two behind. Didn't get into similar positions after but worked hard for his team.
Flicked the ball on to Delph for his stunning strike. Looked to add to his record of goals in two consecutive games but saw Foster save with his toes one-on-one but added one from the spot after he was fouled. Strong and looked back to his best.
Rushed out for the opening goal but couldn't get to the ball quick enough and could do little about an inch-perfect strike from Delph. Made a fine save from Benteke with his toes and soaked up pressure well with a number of top saves.
Looked to create width out on the left and contributed to the opening goal as he placed a pass inside to assist Brunt's early goal. Not the strongest at the back whenever balls came his way and didn't offer enough protection from the wings. His positioning also lacked.
Caught far too forward with balls over the top and was punished for it with Weimann's goal. Had two fantastic chances with headers but missed both and later conceded a penalty after climbing on Benteke. Not his day.
In a defence that played a part in its own downfall in terms of the goals conceded, he was the most steady, jumping high to win a number of aerial challenges and trying his best to cope with the physicallity of Benteke. By far their strongest defender.
He was easily beaten by Delph for their third goal as the midfielder threw a drop of the shoulder and pinged the ball into the net. Did link up reasonably well with Amalfitano in the second-half but still not strong enough at the back.
Brought back into the side to add resliliance to their midfield but found himself the unlikely source of a goal as he broke free of his markers and slotted cooly past Guzan.
Played in a role just behind the main striker and provided energy, driving into the box and firing in a dangerous cross which ended up in the net off Delph. Added a real bite in midfield and was a constant engine in the heart of the team.
Hit a sublime strike from distance in the opening few minutes to put his side ahead. Continued to work hard for his team throughout the game.
Floated just ahead of the back four but didn't offer great protection to his defence and was beaten to a number of balls in midfield. Steady on the ball and generally kept possession.
His first appearance since his 'quenelle' celebration but it was cut short after his side squandered their two-goal cushion and were back on level terms. Didn't look at ease on the right-side of midfield and was hauled off looking injured.
Returned to the starting line-up in place of Vyrdra and became the leading man after Anekla came off. Linked up well for their third goal but should have been closed down. Had a good duel with Vlaar and for the most part came out on top.
