Chelsea youth boss Dermot Drummy says their 3-2 FA Youth Cup win over Manchester United was a great advertisement for academy football.
Chelsea must now finish the job at Old Trafford in the second-leg of their semifinal.
Nathan Chalobah struck twice for the Blues and Drummy told the club's website: "He is almost like an attacking central defender! He can bring the ball out and play but he was also putting in block tackles. He has two more goals and he is still an Under 16 so he is a super talent.
"Aziz Deen-Conteh did well to make the third goal for Bobby Devyne. We wanted to get behind the Man United defence so they were facing their own goal.
"The heat did have an effect. Your brain goes in those temperatures but you have to think quickly and try to control the tempo of the game. We did it first half and they did it second half.
"A lot of these players will be involved in the reserves on Thursday, then we will rest them at the weekend and then travel up to Manchester for what I am sure will be a very exciting game. We are not going to go there to defend. You can't defend for 90 minutes at Old Trafford."
