Yet the arrival of Radamel Falcao wasn’t remotely expected, with the Colombia international moving from Monaco on loan on a dramatic transfer deadline day.
The following year, it was a similar story.
United’s interest in Sergio Romero, Bastian Schweinsteiger, Matteo Darmian, Memphis Depay and Morgan Schneiderlin was all common knowledge.
But, with Anthony Martial, it was a different case.
United needed a striker to replace Falcao and Robin van Persie, who had been allowed to join Fenerbahce.
So the France international, with very little fuss, touched down from Monaco in a blockbuster £36m deal.
