If he was as good as some people are saying, then he'd have played more games. When you cost £20m and you're behind Lallana and Ibe (and occasionally Henderson!) in the pecking order, it says 2 things: 1) you're out of your depth 2) the manager has screwed up.
No doubt he'll play against Carlisle and do enough to convince his fans that he's the next big thing.
