Robbie Savage believes Louis van Gaal will never be able to emulate Sir Alex Ferguson's success at Old Trafford by building a dynasty based on young players coming through Manchester United's youth academy.
Ferguson retired from the game back in 2013 after a glittering 24 year spell at the helm at Old Trafford, having won 13 league titles and the Champions League twice.
He was replaced by David Moyes who lasted less than a season, and now with Van Gaal at the helm the Red Devils are back in the Champions League having missed out last year.

The success enjoyed by the Dutch boss has come at a price however - he spent more than £150 million on new players last year and has made five signings for more than £80 million this time round.
That has led to criticism, most notably from Jose Mourinho, who has accused Manchester United and Chelsea's other rivals of trying to buy the title last week.
Ferguson's most successful teams were based around a core of young players developed by Manchester United, the most famous of which were the 'Class of '92' which included David Beckham, Ryan Giggs and the Neville brothers.
Speaking exclusively to GiveMeSport at a BT Sport media event to launch the broadcaster's football coverage for the coming season, Savage said he had some sympathy for Van Gaal, who he believes would never be given the chance to develop a team like Ferguson because he needs immediate success.
"They’re still bringing players through if you look at [Paddy] McNair and [Tyler] Blackett so they’ve still got belief in their youth system, I think that will never change at Manchester United.
"But I think they’ve realised that they have to qualify for the Champions League so they had to buy players for the here and now, as Liverpool have realised as well. I think gone are the days that you can develop younger players in your team if you want to win trophies.
"I think as a manager, with the time they're given you have to do it [straight away] and have the right players ready."
