Speaking to SportBild, World Cup winner Matthaus ripped into the Leverkusen hierarchy, and Ten Hag in particular, for allowing Xhaka to walk away.
“Xabi Alonso to Real Madrid. Jonathan Tah to FC Bayern. Florian Wirtz and Jeremie Frimpong to Liverpool. Lukas Hradecky to Monaco, and then Granit Xhaka to Sunderland! I can hardly remember seeing a more drastic upheaval at a top team," he said.
“Most of the departures are understandable and couldn’t have been prevented. I just don’t accept that in Xhaka’s case! Erik ten Hag must accept the criticism of not fighting harder for the strategist and the heart of the team.”
