As noted by the Daily Mail, Ighalo's loan deal is actually set to expire on May 31, one month earlier than most other temporary deals, and there is no option to extend that as Shanghai Shenhua initially wanted him back for the start of the Chinese Super League season.
United have the option to buy the Nigeria worldwide on a permanent deal once his loan expires.
Ighalo went on to score a brace against Derby County in the FA Cup the following week before netting during the thrashing of LASK in the first leg of Man Utd's Europa League last-16 tie making it four goals in just 318 minutes of first team football.
However, the Red Devils may have to negotiate an extension with Shanghai Shenhua, who agreed to loan him out to the Manchester giants during the January transfer window, as the Premier League - on hold until April 30 - will probably have to be extended to June.
As a result, a permanent move is seen as a likely solution, with Shanghai Shenhua happy to sell and United eager to buy.
The 30-year-old joined up with Ole Gunnar Solskjaer's squad for the remainder of the 2019-20 campaign in January, having made a transfer deadline day move.
'The challenge before us is not a football one, but a global one. "You can't put football before health challenges".
Ighalo's current loan deal only runs until June but as it stands he would leave before the season is completed.
Ighalo does these things naturally and while he might not be as feted as the likes of Henrik Larsson or Zlatan Ibrahimovic, like them, he's delivered the goods so far and proved to be a shrewd bit of business.
Few expect play to resume then and plans are afoot to extend the 2019-20 season, although whether the Nigeria worldwide will be able to be a part of it remains to be seen.
