"He is a great man and somebody in football who loves his players.
"Gerard lives for football but he must change. It will be difficult for him but he must change something and be more calmer.
"He must be careful in future because life in football is very intensive.
"But it as a good thing for a lot of people that Gerard is back, the players want to win something for him.
"I think Liverpool can be a surprise for the Champions League."
