However, the Frenchman has left José Mourinho in the dark over his whereabouts, and United's manager has admitted that he doesn't know if Martial will return once they get back to Manchester. My little Swan is fine, for the mum it was harder but thanks to God she's better now. Sorry but my family will always go before everything.
But the winger has answered that question himself: he will be back in Manchester tomorrow.
Although United finished their tour of the US with an encouraging 2-1 victory over European champions Real Madrid, Mourinho was distracted by questions around Martial's continued absence.
Asked whether Martial would link up with United, Mourinho said: "Anthony Martial?"

Mourinho was critical of Martial following his failure to return to the United States of America after he left for the birth of his child, and the Portuguese has since stated the "majority" of his players have a fantastic spirit.
And speaking after United's 2-1 win over Madrid last night, Mourinho was reluctant to discuss the situation about Martial.
José Mourinho says he has no idea whether Anthony Martial will join up with the Manchester United squad at Carrington later this week or whether he will feature in their final pre-season game, against Bayern Munich on Sunday.
"I think he's in a fantastic condition, so let's look at it from the positive point of view and wait for Lindelof, Lukaku, Rashford and Jones who are going to be important players for us".
