Speaking to Betfred TV, Robinson said: "He’s a quality player. He’s still only 19 years old and if you look at all his attributes, he’s a dribbler that takes players on. If you play under Ange Postecoglou, the wide players are given the freedom to do what they’re best at. Why weren’t Bayern Munich playing him and why have they let him go?
"Is it the things he’s doing off the field? Could he be a problem in the dressing room? We don’t know. Gametime at Bayern Munich isn’t easy because they’re a quality side, but why have they let him go on loan with a permanent option?
He added: "He’s played 60 games for Bayern Munich and scored 12 goals, so he’s had his opportunities in their first team. I think he’s a quality player, but there’s a part of me that questions why they’ve let him go."
