Bremer will be a massive upgrade. But we will need another CB, preferably left footed one. We cannot go into a season with Gati and Kelly as our options.
But we probably need to lower our expectations of him for next season. Players usually take a season to get up to speed after a knee injury and it's likely that he will have a few muscle injuries.
We need a couple of defenders if we are going to play with 3 at the back.
