Jose Mourinho has made the Atletico Madrid forward his priority target ahead of the upcoming transfer window.
Widespread reports have suggested a move for Griezmann would depend on whether Manchester United had Champions League football on offer.
But with United beating Ajax in the Europa League final last night, the Red Devils now have a much greater chance of persuading him to leave the Spanish capital.
Pogba and Griezmann are good friends away from the field and play together for the France national team.
And it seems the United midfielder is pushing for his international team-mate to join him at Old Trafford.
Antoine Griezmann has been strongly linked with a move to Manchester United
Clearly in good spirits celebrating United's win in Stockholm last night, Pogba added fuel to the fire surrounding Griezmann with his behaviour on social media.
During an Instagram live video the United midfielder mimicked Griezmann's 'Hotline Bling' goal celebration before saying: "Who is that?"
On the United team bus a bit later Pogba then said: “Griezmann is not here… yet!”
Earlier this week Griezmann admitted his chances of leaving Atletico for Manchester were 6/10.

Paul Pogba mimics Antoine Griezmann's celebration on Instgram
And following United's return to Europe's elite competition Griezmann might now rate his chances even higher.
Mourinho however, is refusing to discuss the 26-year-old.
Asked about a move for Griezmann he said: "I do not want to talk about Griezmann because that would be disrespectful to his club, Atletico.
"Just how I do not like others talking about by my players, I’m not going to talk about Antoine either."
