United have already qualified for the Champions League knockout round and Ferguson intends to give his youngsters a chance in their remaining two group games.
On Gibson, Ferguson told manutd.com: "He's not had the amount of football that he'd wish for," said the boss. "I wish I'd been able to give him more games, but he has a lot of competition from Carrick, Anderson, Scholes, Fletcher, and Giggs if I choose to play him there.
"But, credit to Darron, he's never let it unsettle him. His training performances have been excellent. Every session he comes in knowing that it's worthwhile. He has a purpose about his training. For quite a few weeks we've been saying, you can't hold a young one back. They tell you that themselves. And I think Darron is approaching that. He has become a very good, powerful midfield player."
