The type of player Dowell is, he will have periods where he isn't involved, especially at his age. He'll be a cracking player. Really good to see Walsh getting some first team experience, hopefully Redknapps sacking won't hinder him.
...there is a consistent theme that Dowell has match winning ability but goes missing in matches. I love the fella but it's probably holding him back. I suppose the difference with somebody like Lookman is that he might be inconsistent during games but he's still involved and doesn't let his head go down.
There's a bit of luck involved as well, one manager might not rate a player as highly as another. Barkley's rating from Martinez and Koeman for example.
