Manchester United fear losing Odion Ighalo before the season resumes.
ESPN says United are concerned Shanghai Shenhua won't extend Ighalo's loan.
United are concerned this means Shanghai Shenhua will block any attempt to extend Ighalo's loan deal and the Reds do not expect FIFA's advice to change that.
United are keen to have Ighalo available for remaining games in the Premier League, FA Cup and Europa League and have not ruled out signing the former Watford man permanently, but there is an acceptance Shanghai hold the cards in any negotiations.
Ighalo has already impressed during his short time at the club, scoring four goals in eight appearances.
