“You know how it is in football, it’s pre-season, he’s still very young,” Klopp told Liverpoolfc.com.

“He has expectations, I have expectations. He has expectations and that’s good, it’s absolutely good.

“The thing is, the Premier League is the Premier League and we need to make sure he is ready for that. We think he is ready, to be honest, but we have to see when and how often and stuff like this.

“He was injured for a long time. He is a fantastic footballer, we fought really hard for getting him and then keeping him and all that stuff. Now he is here and I think he sees the chance, the chance is there and that’s very good.

“He is an exceptionally good boy and player and I am really excited about the future, but there is not pressure at all on him.

“The big guns are not in and we are all focused and the boys and stuff like that, but don’t put pressure on him. I think he can deal with it because he is a really confident boy, but to be a real Premier League striker you have to miss a chance in front of 50,000, hear the noise, feeling the importance and then if you go again, you have a good chance to be a really big gun.”
