As some eagle-eyed supporters noticed, the Spaniard started following a number of Red Devils stars including Paul Pogba and Ander Herrera.
He even started following some club legends, like David Beckham and Patrice Evra.
United fans, convinced that the Old Trafford club are going to make the 24-year-old their marquee signing, reacted exactly how you would expect.
And it seems Morata has done very little to quell this excitement with his recent Twitter activity – he’s not just limited to one form of social media, it seems.
The Madrid-born forward, who kick-started his career at Real, after spells at both the Atletico and Getafe academies, was sold to Juventus in 2014.
He returned to Real in 2016 but has found cementing a regular place in the first team difficult, hence his reason for wanting a move.
United, who were keen on brining Antoine Griezmann to Old Trafford, turned their attention to the Spaniard when that possible transfer broke down.
As things stand, Real look set to demand more than £60million for the forward, which could provide a bit of a stumbling block.
But none of that matters in the eyes of United fans who have noticed the following – that Morata has removed the fact that he is a Real player from both his Twitter and Instagram bio.
