Frank Lampard was delighted with Christian Pulisic's brace in Wednesday's 5-3 win over RB Salzburg.

Lampard was specifically impressed with the American's desire to take the game on, a quality he will need for success in his debut Premier League season.

Asked about the summer signing from Borussia Dortmund, Lampard said: "He [Pulisic] showed his quality and I love the nature of his goals where he has an intention to run behind the line and not come short and the finishing was good.

"It is what he is going to have to do because he is going to play in the Premier League and the Champions League, this is the top end. A winger has to have the desire not just to be tidy but to be getting in behind people and then with his quality he can be a really big player for us.

"He is a big signing for us with big potential but the big question is he has to adapt to a different league, but I have seen already a really good attitude and a willingness to listen to information.

"He is 20 years of age so we have to remember he is young. I am happy to work with him, I want him to improve him."
