United's season was dismal at best, with the Red Devils struggling to cope with the departure of Sir Alex Ferguson last year. His replacement David Moyes lasted just ten months in the Old Trafford hot seat before the poor results ended in the former Everton boss losing his job in April.
It appears that Holland boss Louis van Gaal is poised to be appointed as the club's new manager this summer, with United poised to embark on a huge shopping spree in order to solve many of their problems around the field, after Moyes was left with an ageing squad.
They have taken their first steps to signing young talent with a reported £27m bid to sign Southampton and England youngster Luke Shaw. The 18-year-old has been one of the stars of the Premier League season, and was today named in Roy Hodgson's England squad, beating Ashley Cole on the plane to Brazil in the process.
Shaw's impressive displays on the South Coast have unsurprisingly attracted interest from bigger clubs in the Premier League, but whilst Chelsea, Liverpool and Manchester City have been credited with interest in the left back, it's United who are the clear frontrunners for his signature.
The rumoured £27m fee seems a large amount of money for an 18-year-old, but United could be able to drive the price down by offering up Dutch left back Buttner in part exchange - especially as Southampton had an interest not only before the former Vitesse man moved to Old Trafford, but also in mid-season when it became apparent that Shaw would be a target for the big boys.
The 25-year-old has primarily been a backup to Patrice Evra at United and is widely tipped to leave the club this summer in order to find first team football, and rather than searching for a left back this summer to replace Shaw, Southampton could simply request Buttner as part of the deal.
It's unlikely that United would say no to such a proposition if meant they could land Shaw.
