Christian Pulisic says his experiences at Borussia Dortmund have prepared him for Chelsea.

The winger signed with the Blues in January but was immediately loaned back to Dortmund, who he joined at the age of 16.

The 20-year-old said: "Going for the title, it's really close.

"I've learnt so much as a player and as a person over there in Germany. It's definitely getting me ready for the big challenges to come.

"[The Chelsea fans] can expect a really good team guy who is going to give everything. He's going to bring his attacking style to the team and do whatever he can to help the team win games."
