I thought he showed some brief flashes of the player he used to be when he came on. He just didn't get much of an opportunity and anyway we weren't playing to his strengths at the time.
It was always going to take weeks or months for him to find his feet again, he's still very much in the process of getting there. To be perfectly honest a full pre-season is probably the only cure for it, but personally I would start him at Wembley and let Grabban come off the bench for once. I didn't think Lewis had a great game overall at VP and probably should have scored - so he might be more dangerous for us if we comes on at half-time or the 60 minute mark, depending on how Kodjia is doing.
