"A good performance helps everyone. It gives them confidence, there’s no doubt about that. It won’t change him. He [De Gea] is a down-to-earth boy.
"As for Danny, his goal won't do him any harm. He's not a boy who lacks confidence. He wasn't fazed by the occasion. It's a great boost for the younger players coming up behind him, those in the Academy like Danny was. He's been with us since the age of nine.
"It's great testament to the development work we do with young players. We had young Nick Powell and Adnan Januzaj in the Reserves on Monday and you say to yourself: 'These are definite Manchester United first-team players.'
"We can see that. They have outstanding qualities. They can see that in trusting us to map out their careers and help them and develop them then they can get to Danny’s level."
Powell impressed in a central attacking role, where he was often employed in his Crewe Alexandra days, against the Gunners' Under-21s while Belgian teenager Januzaj has started to shine at that level after being promoted from the Academy side.
