Manchester United shot-stopper Sergio Romero wants to leave the club in January.
The Argentine is not in the team's squad for the Premier League or Champions League.
Dean Henderson is now the club's no.2 keeper after coming back from his loan spell at Sheffield United.
According to The Sun, Romero is training alone and will seek a move as soon as the transfer window opens.
He has fallen out of favour with manager Ole Gunnar Solskjaer, while he is upset with the club for not making a move easier in the summer.
Romero knows he must find regular game time to stay in the Argentina squad for upcoming tournaments.
