Chelsea boss Graham Potter admits he's unlikely to play any youngsters tonight against Champions League opponents Dinamo Zagreb.
Lewis Hall, along with summer signings Zak Sturge and Eddie Beach, trained with the first team squad yesterday.
However, Potter said: "As I said before I don't think it's a time to be using young players just for the sake of it. I think we have to be competitive and respectful of the competition.
"There are still teams looking for points for their own qualification. So from our perspective we have try and pick a team we think can win the game.
"We've used a lot of young players like you said, a lot of them have been impressive, I like the character, I like the personality and it's been an important part of how we've started here at Chelsea to get closer to the academy guys and to get to know them."
