Manchester United assistant coach Michael Carrick admits he's enjoyed seeing their young players making an impact this season.

United manager Ole Gunnar Solskjaer has put his faith in youth since succeeding Jose Mourinho last December in a bid to revive the spirit of Sir Matt Busby and Sir Alex Ferguson.

Speaking at the premiere of the documentary 'Busby,' Carrick said the current generation must learn from United's rich history.

"It's part of the history and traditions of this club," he said. "It lives on.

"It's kind of the perfect position at the moment for the group that we've got. It's to understand what it takes, the ups and downs that life, not just football, can bring that you've got to overcome.

"To be able to get to the top and stay at the top are different things. The sacrifices you've got to make.

"As a player myself I was hugely privileged and fully aware of the position I was in to be able to represent this club.

"There is a responsibility that comes with playing for this club that probably doesn't come with other clubs. It's got that special nature about it.

"I was fully aware of it and I'm sure the boys now are. Keep playing like that with a smile on your faces and that represents the club the best way you can."

The Geordie added: "I think as a fan – never mind as a coach or part of the staff – to see the younger lads coming in with a freedom and a smile and the excitement of attacking football and feel the energy in the ground – I just enjoyed sitting back and watching it."
