Brentford's co-director of football Phil Giles has said it's important the club learn from the error they made with Alfie Mawson as they look to create a route to the first team for their young talent.
The Bees sold a number of first team players before the close of the transfer window, and after seeing Mawson excel after leaving Griffin Park, Giles says that the club need to do all they can to allow their youngsters to prosper while at the club.
Speaking to the club's website, he said: "We retain a strong squad of young players. I don't see weaknesses in our squad. I don't see fringe players, I see a strong set of B team players ready to come through. So from that point of view it provides a real platform, not just on the pitch but in the sustainability of the club.
"I look back at what happened with Alfie Mawson, and on the one hand we did well to get a good sell-on on Alfie, so it was good business in one sense, but we have to reflect that their was a failing there because we didn't identify his talent and create a pathway to bring him through. So if we hang onto players, and don't create those pathways then the same thing will happen again.
"There are plenty of players in that B team who have the potential to go on a play for us, and we don't want more Alfie Mawsons."
