Wilfred Zaha could be on his way out of Old Trafford just months after joining.
The winger was signed by Alex Ferguson but was allowed stay at Crystal Palace until the end of last season.
However since the start of this season he has only made five appearances for the Red Devils.

It is believed Cardiff are ready to take the player on loan, although Palace may also try to bring him back to his boyhood club with Tony Pulis said to be keen.
