Don't know if it's realistic but his best chance is the change of position. He is never going to make it as a central defender.
Yeah I'm not seeing it. He is a decent defender, albeit quite prone to being manhandled, but he will improve.
When Araujo who earns about less then 1mil, leaves the club because of money he deserves, we will be stuck with this guy who is eaten alive by any strong and fast attacker and who also earns mire then 5mil per year.
Don't see it that way. Players you named are still weakest links in our team + Stegen.
