Yes, consistent is what Ash was last season. Not spectacular, never bad. In terms of defending 1v1 he is still the best in the world. However his touch is average, his crossing is weak and his final ball is rarely accurate. As another poster mentioned, he is heavily reliant on his left foot which makes him less of an attacking force.
If you watch Coentrao play, this guy is very versatile, very skilled in 1v1 attacking situations and penetrating runs, great crosser. He starts attacks and can finish them with great passes. He was also considered the best LB at the World Cup by many.
I think its time to let Ash go. He has personal issues, he has injuries, he is 30. If we could get 25 mil for him we would be crazy not to sell.
Plus, the way this story is shaping up, looks like Real want Maicon desperately which would free up Sergio Ramos. Maybe we send Ash in a straight swap for Ramos, Real signs Maicon to fill their RB position and we sign Coentrao to fill our LB spot.
