Gjanni Alioski handed the Whites the lead in the first half with Marcelo Bielsa's men putting in a gritty performance to hang on for all three points in LS11 as Slaven Bilic's side tested their defence in the closing stages. Here's how we rated the performance:
7. Mateusz Klich
7 - Creative in the first half, workmanlike in the second. Had sniffs of goal but couldn't convert. | jpimedia
8. Helder Costa
7 - Better than Saturday by a long way. Much more dangerous. Caused West Brom problems. | jpimedia
9. Jamie Shackleton
7 - Lightning quick breaks seem easy with a central midfielder who can shift like he can. Good on the ball too. | jpimedia
10. Jack Harrison
7 - Teed up Alioski for the goal after creating space. Second half dug in like his team-mates. Could have won it late on, a little wasteful in that regard. | jpimedia
11. Patrick Bamford
8 - A battling display. Should have scored in the first half. Could not have put more effort in. | jpimedia
12. Gaetano Berardi (sub)
7 - Quietly went about his business. Did little wrong. | jpimedia
