Had little to do in the first half as Villa were restricted to long shots at goal but was well beaten by Kozak's half-volley which hit the bar. Rushed to close down El Ahmadi for his goal but didn't get close to the Villa midfielder. Had no chance of stopping Westwood's equaliser.
Had a solid game at right-back but the 32-year-old was rarely tested due to Villa's lack of width on the left.
Was posed few problems in the first half as Villa opted to play narrow but the 29-year-old's abysmal header from Agbonlahor's cross fell to Westwood, whose strike secured a point for the visitors. Was brought off for Anichebe not long after the mistake.
Handled Benteke impeccably alongside McAuley and was given little trouble by the Belgium international. Let down by Popov's woeful clearance which allowed Villa to steal a point.
Coped well with the threat of Kozak and Benteke alongside Olsson and restricted the chances of Villa's attacking duo to mainly long-distance efforts.
Missed a great chance to put West Brom three ahead from five yards out. Squandered another opportunity from close range after the break which would have put his side out of sight. Brought off for Morrison after 73 minutes.
His excellent 45-yard pass assisted Long's opening goal and the 28-year-old always provided West Brom with an outlet on the left flank.
Kept West Brom flowing with pass after pass. Rarely looked flustered alongside Mulumbu and worked well to overcome Villa's three-man midfield before Lambert changed his side's system.
Constantly attacked Clark on West Brom's right flank and provided an excellent cross for Sessegnon, who squandered the chance from close range. Faded as the game progressed.
Was often West Brom's driving force in central midfield and showed good composure on the ball alongside the equally impressive Yacob. Booked.
Opened the scoring after three minutes with a superb first touch and driven finish. Doubled his tally with a deft chip over Guzan. Looked lively all evening and was West Brom's brightest outlet.
Could do little about either of Long's goals in the first half since both were fine finishes. Wasn't tested as much in the second half as Villa crept back into the game.
The centre-back's last-ditch challenge denied Long a chance to seal his hat-trick in the 29th minute. Looked the more solid of Villa's centre-back duo.
The 22-year-old was completely outfoxed by Long's excellent first touch for the opening goal and couldn't get close enough to the Republic of Ireland international for his second of the evening.
Set out his stall early on with a few strong challenges on Amalfitano and handled the on-loan Marseille midfielder well. Booked.
Struggled to get on the ball in the first half and could not provide the link between Villa's midfield and attack. Hauled off after 57 minutes for Weimann.
His loose pass was intercepted by Long and the striker took full advantage of the mistake to put West Brom two ahead. A poor cross from the right-back in the 67th minute resulted in Villa scoring their goal, however.
His blistering strike from outside the box rescued a point for Villa and the 23-year-old was the most composed on the ball for the visitors throughout the evening.
Slack in possession throughout the match and contributed little to stifling West Brom's attacks in the first half. Lasted 12 minutes after the restart before being replaced by Delph.
K. El Ahmadi
Showed good alertness inside West Brom's box to bounce on Weimann's header and steer the ball past Myhill. Overall, the 28-year-old could have been better in possession in Villa's midfield.
Was often pressed quickly by the West Brom players and struggled to find any rhythm as a result. Had a half-chance inside West Brom's but blazed his effort wide.
Clipped the bar with a half-volley after combining with Benteke but was one of many quiet Villa players in the first half. Brought off in the 57th minute for Agbonlahor.
Saw little of the ball after coming on and was the most muted of Lambert's trio of second-half substitutions.
Almost pulled Villa back into the game but his deflected effort was saved by Myhill. Managed to get his head on Bacuna's mishit cross which provided a wonderful assist for El Ahmadi's goal.
Provided the width which Villa desperately craved in the first half and his cross led to the visitors' equaliser.
