You're correct to some degree; he's certainly a good link up player who has capable defensive aspects to his game. He's also experienced.
Nevertheless, my concern is more to do with our overall style of play and in particular our tempo. I question how Cleverely will improve this.
Allardyce knows that his team have defensive frailties, and as such will most probably come (as usual) to stifle us with a rigid defence.
I am concerned that our slow build up play with struggle to unlock this: simply passing across in front of their lines as we often end up doing.
Now some may argue that this can negate the need for wingers if they're struggling to get behind, but personally I'd like to stretch them.
I'd like to see someone who can open up the play, try to get behind them and whip some balls into the box; play with a high tempo et al.
For all Cleverely's positives (I am happy he is here), I can't see him utilising these on the left as much as someone else may. It'll end up narrow.
Certainly he'll open up more space for Barkley and he'll cover at the back, but I can't see that being too much of an issue throughout the game.
As
@Saint Domingo said, really he should be in the middle, but Martinez doesn't really like playing two wingers so I'm just talking needlessly.
