The French forward was linked with the Red Devils earlier this season but after the La Liga side received a transfer ban he opted to stay at the club.

But now Spanish outlet Don Balon say Griezmann could take up an offer to join United or Barcelona if Oblak is sold.

The reports claim the Atletico man is unhappy Diego Costa hasn’t joined yet and does not want the goalkeeper to leave either.

Oblak has been linked with a switch to Paris St-Germain who have already signed Neymar in a record-breaking £200m deal this summer.

Earlier during the transfer window Griezmann admitted there was a 'six out of 10' chance he would be plying his trade in the Premier League shortly.

But that was before he seemingly committed himself to Simeone’s side.

Griezmann hit 26 goals from 53 games last season, making him a man in demand this summer.

New Barca boss Ernesto Valverde is keen and Mourinho has the France international on his wish list.

Antoine Griezmann has made a demand to Atletico Madrid and could still join Man Utd

That’s despite the Red Devils already adding Romelu Lukaku to their ranks who scored twice at Old Trafford in the 4-0 win over West Ham earlier today.

What Griezmann decides will hinge on whether Oblak remains at Atletico or is allowed to leave by Simeone.
