Manchester United should be allowed to sign a replacement for Odion Ighalo if they are not able to keep him on a permanent basis.
That is the view of former United striker Dimitar Berbatov, who claims it would not be fair if they were left a man short. Red Devils boss Ole Gunnar Solskjaer says the club are currently "in dialogue" with Shanghai Shenhua to extend the loan deal of the Nigerian.
The 30-year-old moved to Old Trafford in January and will return to China on May 31 unless an agreement can be reached to keep him until the end of the season.
The former Watford striker was brought in as cover for Marcus Rashford on transfer deadline day and has impressed by scoring four goals in eight appearances.
