The Nigerian forward completed a return to England on the transfer deadline day to team up with Ole Gunnar Solskjaer's side
Former Manchester United centre-back Jaap Stam said Odion Ighalo's signing is an opportunity for the forward to score more goals in the Premier League.
The 28-year-old completed a late six-month loan deal from Chinese Super League club Shanghai Shenhua to Old Trafford on Friday, three years after he left Vicarage Road.
Ighalo is the first Nigerian player to join the Red Devils, and he is expected to boost their attacking options with Marcus Rashford ruled out for a couple of weeks with a back injury.
