Interesting. I've always rated both players, Lewis always seems very committed and I don't think he gets enough protection. It's always going to be tough to look good in a team that consistently wins trophies, you don't just have to be good, you have to be the best and that's going to take time for them to develop.
As for Doku I've never understood why some think so poorly of him. It's clear that he always ties up at least two defenders every time he has the ball so he's taking players out of the game, and we don't use that strength enough. He needs better movement from those in the middle, he can't be expected to beat 2-3 players, get to the line and put in a perfect cross when there are another four defenders between him and our nearest attacker but that's what consistently happens. I think that will improve now we have more players with pace going forward, such as Marmoush, Reijnders and Cherki.
He didn't get a lot of service yesterday, there was definitely a bit of a disconnect on the left side of midfield but that could be partly due to the way the opponents play, and it will be different every match. I think too many expect them to provide the same quality of service every match but that's never going to happen, people need to be more realistic.
