Manchester United moved late on Deadline Day to sign Odion Ighalo from Shanghai Shenhua on loan until the end of the season.
The deal for the 30-year-old, who previously played in the Premier League at Watford between 2014 and 2017, does not include an option to buy.
Ighalo is due to fly to the UK from China, where he has played for the last three years, over the weekend.
He scored 16 goals in 55 Premier League appearances for Watford before leaving for China and will provide short-term cover for the injured England international Marcus Rashford.
The striker finished as top scorer in African Cup of Nations qualifying for Nigeria with seven goals, before scoring five at the tournament last summer.
