To me he's not doing anything different to what he was doing in Germany. When I watch those highlight videos people post, I see the same movements, the same intensity its just that the defenders in England are that much faster, stronger, and overall better. He's a lot like Depay in that he looked better in Europe than he did in the league, because the (mostly physical) standard is lower. He's never passed the eye test for me, although I do think he's very good at slipping those passes through the backline. When we were signing an English left winger Grealish was the one to sign.
