The 30-year-old joined United on loan from Shanghai Shenhua for the remainder of the season on deadline day and arrived in Manchester from China on February 1.
Ighalo has not played a competitive match since December 6 and has been building up his fitness ahead of United’s Premier League fixture against Chelsea on Monday evening.
However, instead of carrying out his fitness work at United’s training ground, the Nigeria international has been training at the National Taekwondo Centre in Manchester since arriving in England.
According to The Times, United’s medical staff believe the chances of Ighalo having coronavirus are ‘remote’ but the striker has been told not to visit the club’s Carrington training ground as a precaution.
The worldwide death toll due to coronavirus now stands at over 1,350 people, while over 60,000 have been diagnosed in China. Nine people in the UK have tested positive for the virus.
Meanwhile, United’s first-team squad flew to Spain last Saturday for their warm-weather training camp in Marbella.
Ighalo will link up with his new United teammates at Carrington on Saturday, while Ole Gunnar Solskjaer has confirmed that the striker will be part of the squad that travels to London for the game against Chelsea.
‘We will just see his fitness work this week and I think we will get him sharp,’ said Solskjaer. ‘We want to integrate him as quickly as we can because, of course, he is desperate to play for us.’
