The former United midfielder does not believe Manchester United's midfield can compete with Chelsea and Manchester City's.
Manchester United were the biggest movers in the Transfer Market this summer spending a heap of cash on the likes of Luke Shaw, Ander Herrera, Daley Blind, Marcos Rojo, Angel Di Maria and Radamel Falcao. But even with these incomings it is believed that the club missed out on some targets this summer - namely Arturo Vidal of Juventus.
The Chilean was heavily linked with a move to Old Trafford this summer, with a reported fee of £34 million being mooted in some circles.
United were reportedly looking for some extra dynamism in the heart of their midfield this campaign, with Vidal the perfect option to complete such a role. However, as time went by it became apparent that Vidal was heading nowhere. At one point he looked like he might be on his way, but with days to go before the window closed it was confirmed in Italy that Vidal was not going to leave the club.
Not only did Juventus not want to sell him, but United began to have reservations of their own. Vidal's trick knee had them worried and in the end both parties seemed to agree that right now, no deal would be going ahead.
But one former Manchester United player who believed he was perfect for Manchester United was Owen Hargreaves. A £17 million arrival from Bayern Munich in the summer of 2007 Hargreaves arrived off the back of some excellent form for England.
Of course it never worked out for him at Old Trafford. He suffered with serious knee injuries throughout his time at the club and was called one of Sir Alex Ferguson's worst signings by the man himself.
He was a gamble because of a known proneness to injury, as would Vidal be, which did not pay off.
But Hargreaves believes Vidal would have been perfect for the club, before his knee injury:
“That’s where United are behind [Manchester City and Chelsea]. Michael Carrick is great for them because he’s a great passer of the ball but I still think you need a physical, athletic presence in that team that can have an impact.
“You look at the United side, there’s not a lot of speed really in there...
“They already have Carrick and I think he needs to play but I think if they are going to sign a player they need somebody they don’t already have.
“Somebody physical, a great athlete but that can still play.
“I think [Arturo] Vidal before his injury looked like he was going to be that player."
Given the club's history on gambling on industrious, energetic, midfielders with a propensity to become injured it is likely that United will steer clear of Vidal for now.
