The 29-year-old midfielder is out of contract at Old Trafford at the end of the current campaign and appears unlikely to sign a new deal.
The England star, who spent the second half of last season out on loan at West Ham, has been linked with a move to Newcastle in this month's transfer window but it seems the deal is at risk of collapse.
While recording on social media a fan, on the account @phezthered, asked the German for an update on Lingard's future and pleaded for him to stay because he's "my favourite player" and "has got United in his head".
Then, as he finished writing an autograph, Rangnick looks up at the supporter and says "he will leave in the summer".
