It's not beyond the pale to suggest Wells should get dropped.
"With great power comes great responsibility." It isn't as if senior players in any team in history haven't been dropped as a message, example or wake up call. If it never happens I don't think it's unreasonable to think that the player has a certain (unconscious) complacency. A term that isn't inconsistent with Wellsy imo.
If everyone plays their part Wells isn't indispensable; if he is, god help us when he retires. I thought that, when it was hot in the kitchen (or should have been) he was largely absent. His performance is worse when you consider what he's capable of.
Will he be dropped? Of course not. But if he was it'd raise a few eyebrows and give genuine hope to those on the fringe that there is realistic hope of being rewarded for effort.
