Chelsea boss Thomas Tuchel says Timo Werner must build on today's goal in victory over Club America.

Werner came off the bench to score in victory in Las Vegas.

Tuchel said, "We need to see, but everybody is responsible for their own situation, as is Timo. Timo played 45 like everybody else, and he scored. That's what counts, and from there, we go. There is always stuff to improve, but it's the first match. Kai (Havertz) had a big chance, Michy (Batshuayi) had a big chance, Timo took his chance, and so did Mason (Mount).

"I count on the facts they become more experienced and maybe more calm and adapt more and more. They are still young players, and this is what we want from them: that they stay confident and stay focused and do what they need to do as strikers."

Tuchel also spoke of Conor Gallagher's performance after his return from last season's loan with Crystal Palace.

He stated: "With Conor, the same as a midfield player. Conor trains at a really high level, and you can clearly see it was the right decision to let him go on loan. He made a huge step in his development at Crystal Palace and became an England player. We can see this clearly in training. It was a very good start and a good match for him.

"Now, for him, it's important he gets used to our principles of the game, to understand when to move and when not to move, and his work rate is outstanding, and he has such a big heart. He can be a big asset for us."
