Ryan Giggs urges Manchester United's youngsters to make a big impact in the first team

Ryan Giggs has urged Manchester United's youngsters to seize their chance to impress in the last few games of the season.

Manager Sir Alex Ferguson can assess his options for the next campaign after United regained the Premier League title with four games to spare.

Belgian teenager Adnan Januzaj has been added to the first-team squad as they prepare to face Chelsea on Sunday and Giggs believes the young players must make a big impact if they are to remain at Old Trafford for the long-term.

"I have seen so many young players over the years have a chance and not really take it," he said.

"Others think 'this is my chance I am going to make sure the manager takes notice' and they perform like they have been doing in the youth team or the reserves.

"Nick Powell did it earlier this season. He came on against Wigan and scored. That is what young players have to do."

Giggs would move onto 937 appearances if he faces Chelsea this weekend, but the Welshman insists he has not lost any of his passion for success during a 22-year career.

"The hunger comes from a lot of things," he said. "First and foremost it is about enjoyment. I enjoy the challenge.

"Obviously I am coming to the end of my career, so I am thinking could this be my last chance to win a trophy.

"But retaining hunger is not something I need to try for. It just happens.

"You have to do it at this club. When you go out at Old Trafford, you have to perform. In away games it is the same.

"That comes from making sure I am ready for the game by what I do in training. I have done that for so long I just carry on."
