it's debatable. did kepa warrant that huge transfer fee? does de gea deserves being the highest paid GK in the world?
Ter Stegen demands to be the highest paid goalkeeper in the world.
Fee and wages are an entirely different matter.
But seriously guys - y'all need to get a grip. MATS is a great keeper. Until the new contract thing materialises, leave him be. He'll save you plenty of times to come, including the CL.
