Chelsea U21 coach Mark Robinson was delighted with Tyrique George after victory over Luton.
Midfielder George scored in the 2-1 Prem 2 win after being promoted from the U18s.
Robinson told the club's website: "I'm obviously really pleased that, as an Under-18, when Tyrique's stepped up he's done well with us. He's got lots of quality and it's about making him more consistently effective.
"He's got great ability but I believe he can affect the game even more. So when he gets those opportunities it's about improving him in terms of the quality in possession, as it is for a lot of the players
"I'm really pleased that we got Ollie Harrison on, as he's only 16 and it's great experience for him, and he found the first pass forward for Tyrique's goal. It was really pleasing to get him involved, and Kaiden Wilson as well, another Under-18. Putting them on, when Luton had just got back to 2-1 and the crowd were at their noisiest, it was great experience for them at the end."
