9. Alexis Mac Allister 7/10
Arriving late in the box and finishing well is a nice habit to get into. Did it against Pompey and he did it against at Preston as he added Albion's second. Unselfishly tried to pass to Gyokeres on 44 minutes when he was well placed to shoot. Decent display and good workrate.
10. Jahanbakhsh 7/10
Another cracking goal for the Iranian as he fired home a lovely first time effort from Bernardo's cross. Was lively for Albion and also forced a smart stop from Ripley at his near post in the first half
11. Gyokeres 6/10
Ran into space and always looking to make himself available. No clear cut chances for the Swedish international striker. Did his share of defensive work too and enjoyed a great tussle with Bauer
12. Cochrane 6/10
Got three minutes at the end as a replacement for Sanders
