Atletico Madrid forward Antoine Griezmann has admitted that he is unsure when his future "will be resolved".
Griezmann recently revealed that he would be leaving Atletico this summer and Barcelona were considered to be the favourites for the attacker.
However, United are said to have made contact with the 28-year-old to discuss a possible move, amid suggestions that Barca could drop their interest.
Griezmann was on the scoresheet in France's 2-0 win over Bolivia in Sunday night's international friendly and the former Real Sociedad youngster gave an update on his future after the clash.
"I do not know when my future will be resolved. It is a good question, but everything will come in its time," Marca quotes Griezmann as saying.
The forward, whose release clause will drop to £104m at the start of next month, has netted 133 times in 257 appearances for Atletico in all competitions.
