Feels like a lot of people underrate Bernie's contribution but one man who we can be sure doesn't is Pep.
I think someone earlier in the thread used the word knit and it applies to Bernie, hes one of those players who provides glue to the team, as does Gundo, and are often unsung compared to those whose numbers look more spectacular in the face of it.
If Bernie wants to leave to get more game time, or even be allowed to play with more freedom, then so be it but I do not see City trying to move him on and nor should they.
