7. Mateusz Klich
9 - Workrate was excellent first half, shrugged off the weight on his shoulders with a goal then added a sublime second. | jpimedia
8. Helder Costa
8 - Got at Boro when he could, looked dangerous without adding a final product in the first half, scored an excellent goal in the second. | jpimedia
9. Jack Harrison
8 - Started the game brilliantly and had a part to play in the second goal. | jpimedia
10. Pablo Hernandez
8 - Found pockets of space, made clever passes, not always with his usual accuracy. Supplied a wonderful assist for Bamford. | jpimedia
11. Patrick Bamford
9 - Took his goal well, could have had another soon after, showed his physical side and the side opposition fans hate. Dominant. | jpimedia
12. Eddie Nketiah (sub)
