Speaking to BBC Sport, the Blues manager said: "We are all former players. All of us went through some bad moments. You cannot expect Palmer to be like he was last season or how he was in the first part of the season. It's normal. He is human. I was telling him it was normal. He is happy. He is OK. He has shared the changing room with some top players and he knows that every top player goes through bad moments. It's about how you react. Keep working, keep laughing, keep calm, be happy and enjoy the football. It's the only thing you have to do."
