After a stunning start to the season from the likes of Chris Smalling, Phil Jones and Tom Cleverley, United legend urges them to continue making an impact to hold onto their places
English trio Chris Smalling, Phil Jones and Tom Cleverley, as well as Jonny Evans and Brazilian midfielder Anderson, have all been outstanding in United's start to the Premier League season, which has encompassed a maximum 15 points and wins against Arsenal, Chelsea and Tottenham.
And Giggs has told United's youngsters that they must continue to show a high level of commitment, on and off the pitch, if they are to remain at United for years to come, and if they are to relegate senior colleagues, like Rio Ferdinand and Michael Carrick, to the substitutes bench on a permanent basis.
"It is tough because there is a lot of quality in the first team," Giggs told MUTV.
"The majority have the quality. That is not really in doubt. The question is, do they have the desire and appetite to take it up a step more?
"There are young players coming through at United but this is an important part of their career. When you look at the lads who came through in my age group, then those who followed; Wes Brown and John O'Shea for instance, when they got their chance, they took it.
"Once you hit 17, 18 and 19, that is what you have to do. It doesn't matter whether it is if you get a chance to train with the first team, or in a match as a substitute, you need to make an impact.
"You need to force the manager not leave you out of the next game."
