Sacking Ole would be silly; talking about it is also silly. He has moved the club forward and he can move the club forward even more. Only when we think he can't move the club forward any more should we sack him. The club needed a refresh. It didn't need someone to sign Ibrahimovic and limp into the top 4.
Lukaku didn't fit the style Ole wanted to play. I'm glad he has gone. At some point we will need to sign a striker who fits our playing style and is committed. Until that happens no point in signing someone random. Realistically, it will be 3 seasons before this squad can compete for a title anyway.
