Yes his best position is undeniably from the left. That's where he's had his best stats from. At Dortmund:People keep saying he's a right winger playing out of position, but wasn't it shown that his stats were better off the left than the right or am I making that up?
Somehow I don't feel that position has much to do with things at the moment, it doesn't seem like it's causing him the issues. In fact I would say right wing is a harder position to come into because our right side is a bit of a wasteland.

Position is definately not the problem, his problem is the adjustment moving from a well coached side like Dortmund to... us. He's playing wide on the left without much support around him. That's not his game, he's not a runner like a Rashford. He cuts inside and drifts, playing neat 1-2's, similar to how Hazard was at Chelsea. Take the weekend, he was very lively vs Everton, but they were able to crowd him out with 2/3 players every single time. He'd beat a man, then there was another right on him, with no-one to support him. It was the same story vs. Villareal too. We're never going to see the best of him if it's like that.
