However, the striker won't feature in today's friendly against Hertha Berlin.
Klopp said: “Danny will not be in the squad, for him it is too early - but Sadio (Mane) will be in the squad for sure.
“Danny looks good – fantastically actually – but playing is a little bit different. We thought about giving him the opportunity to play with the U23s because we have the opportunity, especially with the strikers, but it makes not too much sense.
“We wanted him here so he really could train with us, but he will not be in the squad tomorrow."
