Manchester United were expected to spend heavily this summer in order to erase the memory of the dismal David Moyes era - but few could have expected the mass transfer spree that United have conducted in recent weeks. It was a slow start to the transfer window for United, as only Luke Shaw and Ander Herrera arrived from Southampton and Athletic Bilbao respectively.
However, the 2-1 opening day defeat has sprung United into action, with Sporting Lisbon defender Marcos Rojo arriving for £16m after an impressive World Cup campaign for Argentina, and his international team mate Angel Di Maria joined him at Old Trafford as the club's marquee signing in a £60m deal from Real Madrid.
New manager Louis van Gaal then snapped up his Netherlands World Cup star Daley Blind for £14m from Ajax, but that deal was eclipsed as Monaco striker Radamel Falcao joined in a shock loan deal. With 200 goals in 305 club games across spells with River Plate, Porto, Atletico Madrid and Monaco, the Colombian is one of the deadliest strikers in world football - or at least he was.
In January, Falcao tore his anterior cruciate ligament, ruling him out of the rest of the season and the World Cup - just six months after being linked with a big money move to United. It's a notoriously difficult injury to come back from, but he can look in the direction of a United legend for proof that he can return to top form in front of goal.
Ruud van Nistelrooy was set for a move to United in 2000, but saw the deal collapse after he tore his ACL in training. He was sidelined for almost a year, but finally made his switch to Old Trafford from PSV Eindhoven a year later - somewhat similar to Falcao's deal.
Van Nistelrooy became a United hero from then on. With a staggering 150 goals in 219 games, van Nistelrooy was nothing short of a goal machine at Old Trafford before his 2006 move to Real Madrid. The Dutchman needs to be the blueprint for success for Falcao, and he possesses some of the same predatory instincts of van Nistelrooy in his prime.
Whilst Falcao is only on a year-long loan, there appears to be the option of buying him next summer - and if he can replicate van Nistelrooy's success, then he may be at Old Trafford for years to come.
