Paul Pogba was absent from Manchester United training on Wednesday, following reports his girlfriend has given birth this week.
Pogba's form has improved since Ole Gunnar Solskjaer returned to the club as caretaker manager and he produced another impressive display on his return from a leg injury as United beat Tottenham on Sunday.
But the 25-year-old was not part of United's session at Carrington on Wednesday, ahead of Saturday's game against Brighton.
Nemanja Matic was also missing from training after his wife gave birth earlier in the week.
Alexis Sanchez missed the victory over Spurs with a minor issue, but the forward was in action at the Aon Training Complex on Wednesday morning.
Chris Smalling has yet to return from a foot injury, while Marcos Rojo is also undergoing rehab.
Former United striker Giuseppe Rossi was part of the group as he looks to build fitness and earn a move elsewhere.
Solskjaer admitted on Tuesday that Sir Alex Ferguson, a regular visitor to Carrington in recent weeks, had been impressed with Rossi's finishing in training.
