#1 Zlatan Ibrahimovic

In the Alex Ferguson days, Manchester United would not only attract big name stars, but it would also get the best out of them, and it is this that has been a major problem for the club since the Scotsman left.
Players like Radamel Falcao, Angel Di Maria, and Memphis Depay, have all arrived at United riding a wave of momentum, only to fail miserably when they've walked out at Old Trafford.
One player who truly lived up to his reputation, though, was Zlatan Ibrahimovic. The iconic Swede arrived in Manchester at the age of 35 and proved that he still had plenty left in the tank.
Zlatan and Manchester United felt like a match made in heaven, and the Swede would go on to score 28 goals in his debut season for the club.
Zlatan's second season at the club was plagued by injury, but the Old Trafford faithful will forever be grateful for the Swede's contributions to the club.
