Chelsea attacker Christian Pulisic has no doubts Timo Werner will prove a big hit.
The former RB Leipzig striker has begun training with his new teammates.
"He's a very dangerous player," Pulisic, who arrived a year ago from the Bundesliga, said. "I think he has some similar qualities to me and some of the attacking guys we have. He's obviously very quick and very good in front of goal.
"He seems like a very humble guy. He wants to come in and wants to work. Playing against him has been a great experience and it's going to be nice to have him on my team as well. So I'm definitely looking forward to that."
