Two things:
1. Werner is low on confidence. I don’t think he’s recovered from playing under Fat Frank. But he has still got the skills and pace that saw him become one of the hottest prospects in Europe.
2. The way Werner plays, and indeed the way he was playing during those golden years, is very much in keeping with Postecoglous ethos - quick fluid moves to unlock the opposition. Both of them are aligned. Werner’s strengths are attributes Postecoglou looks for. Can beat a man. Can outpace most defenders and does well with quick fluid play.
Psychologically I don’t think Werner has recovered from his experience at that brickry club in west London. Can’t be easy going back after a failed move. And he’s been in a funk since. Now it’s time to step up, regain some confidence and play some fluid, quick football with Son, Maddison and Kilu.
