I think Lingard & Mata are kinda getting a little taste of what Ramsey went through with Alexis's undisciplined selfishness. Lukaku too. He cuts into their space & treads on their toes. He's even hurting Ashley Young's form. Ramsey & Nacho have both flourished since he left.
In fairness to Wenger it was a tricky situation cuz Alexis was a stone cold finisher who could guarantee you 50 starts a yr. Ramsey did get fd about a lot though.
Ramsey's injuries have hurt him. A good long run in his preferred position would do him the world of good. Lets see if he can hold up to the rigours. I'm a fan. He has quality in his feet.
