Dont look at Auba being the problem. Look at Tuchel willing to be flexible to accommodate Auba‘s strengths. He wasnt willing to do that with Lukaku so i dont see this working out either.Auba to Chelsea is....weird.
I get their need for a striker for SURE. But we'll see how he gets on with Raheem and Kai. I think they'll find form again. But if they'll challenge for Europe at this point we'll see. If Auba goes down injured they are RIGHT back where they started.
