Despite spending a king's ransom this summer on signing both Zlatan Ibrahimovic and Paul Pogba, it seems Mourinho won't rest until he's bled Old Trafford dry of every last penny. Their next target? Trendy French forward Antoine Griezmann who United fans are keen to get their hands on given their less than critic-crushing season.
One person who has been particularly enjoying the rumours is Antoine's brother, Theo Griezmann, who earlier this week tweeted a dig at Memphis Depay following his start for Lyon after leaving United.
And he wasn't done there. Theo took the wind-up one step further yesterday by tweeting a picture of Old Trafford with no accompanying caption.
Unsurprisingly fans lost their marbles at whether he was joking or leaving clues:
If he isn't mercilessly trolling fans and Antoine really is headed to join fellow national player Pogba, something must have really changed after he pointed at the pitch in Madrid and screamed, "this is my home."
