The brother of Atletico Madrid striker Antoine Griezmann has teased Manchester United fans by posting an aerial image of Old Trafford on Twitter.
United are interested in signing the France international, with Jose Mourinho keen to make him his marquee signing next summer.
Reports over the weekend claimed Griezmann has already agreed a wage and the No 7 shirt number ahead of his move to the Red Devils.
And his brother Theo, who trolled Memphis Depay following his move to Lyon last week, has dropped a huge hint that the 25-year-old is heading to United.

1 of 10
Who could Jose Mourinho sign in January?
Harry Redknapp has urged United captain Wayne Rooney to find a new club this month as Jose Mourinho does not considered him a nailed-on starter.
"Mourinho doesn't see him as a starter. He doesn't think he is better than Zlatan," Redknapp told talkSPORT.
"Maybe it is time for him to have one more challenge – go somewhere where he is wanted and going to be a big player.
"He could go back to his own club Everton. He is an Everton fan. Go back there, finish your career there and take Everton into the Champions League positions."

Goncalo Guedes undergoing Paris Saint-Germain medical
United have been dealt a huge blow in their pursuit of Benfica forward Goncalo Guedes.
The 20-year-old has been linked with a move to Old Trafford this month, with Portuguese newspaper Record claiming Jose Mourinho sent scouts to watch him in action.
But Transfermarketweb claim that the Portugal Under-21 international is having a medical at Paris Saint-Germain ahead of a £21m move.
