Manchester United manager Ralf Rangnick has refused to sanction Jesse Lingard's move to Newcastle United.
The Magpies have pushed forward plans to sign Lingard, who is out of contract this summer.
ESPN says Rangnick has told the club not to sell the English playmaker.
Tottenham Hotspur and West Ham Unite have both had approaches for Lingard rejected this month.
Rangnick's main concern is that another Covid-19 outbreak decimates his squad as United look to compete in three competitions.
Lingard wants to leave United after being kept to just two starts this season.
Barcelona and AC Milan are also interested in signing Lingard when he becomes a free agent.
The 29-year-old has expressed a desire to test himself in a foreign country.
