I don't think they will strugle so much when Mourinho will leave. They have the expirience, knowledge and some beliefe that is already installed in them so I think they will do quite good after mourinho will leave and I think they will be competative without him too.
i just hope that we take the right steps forward and retain our character to be able to compete with them, because we have a lot of old players who might leave or retire and there will not be a stable transition of attitude to the younger players, certainly not with the board couches medics we have right now.
