I think those that are critical of this seemingly inevitable signing haven't seen enough of him this season, especially since Sherwood was appointed.
He has good ability on the ball, can take it under pressure a la Pienaar and is a bit of a snide in a tackle which we all love.
Most importantly he distributes the ball QUICKLY. That's his major asset. How many of us have voiced our concerns at the laborious, pedestrian-like possession of the ball. Last season we simply didn't move the ball quickly enough, a criticism of Besic, McCarthy, Barry..... Cleverley will get us moving quicker, get the ball wide quicker and simply make us more positive.
Again, I would suspect that those who don't perhaps appreciate this are taking the ridiculous anti-Cleverley social media campaign into consideration rather than watching the lad yourself.
