Henderson admits he cannot wait to link up with midfield colleague Gerrard.
"He is one of the best players in the world, you want to be playing with him and training with him to try to improve yourself as a player," Henderson said.
"I've trained with him once (for England) and he was unbelievable, to be honest. I'm looking forward to it, and there are other good players here who can help me as well.
"Steven has been a massive, massive player for Liverpool for years now and he still is. Hopefully I can learn a lot from him."
