Once you’ve gone through this process and everyone understands that you belong, everything gets easier – from the players, the supporters, the media and the opposition.“But you have to go through this process. I trust myself a lot and I think I’m ready for the challenge that I know is very big. “When I came here, the owners told me everything is not perfect.“They said we would have some challenges, we would have to replace important players leaving, we have some injuries, but we are here to solve these problems and to maximise what we have.“In my opinion, we have a very good squad.”
