Gilmour won two straight man-of-the-match awards before the Premier League season was suspended to the coronavirus outbreak.
Gallagher impressed on loan at Charlton for the first of the season, and now he's at Swansea City. And his potential has impressed Curbishley.
"You saw Billy Gilmour [recently] and there are some good players coming through at Chelsea," Curbishley told Goal at the London Football Awards. "He needs to be playing, Gallagher has shown that this season that playing regular football has helped him enormously.
"He can play for Chelsea for sure in the future. He has got box-to-box energy, can find a pass and score a goal. He is a team player and a good lad as well, as I understand it, which helps."
