Alejandro Garnacho has been reprimanded after upsetting Erik ten Hag and his team-mates by undermining the Manchester United manager on social media.
Garnacho liked a post claiming he was 'thrown under the bus' by Ten Hag when he was substituted at half-time of Saturday's 2-2 draw at Bournemouth.
The United manager was said to be angry with Garnacho, and other players also felt let down by the Argentina winger.
Garnacho was brought into line when Ten Hag spoke to him at training on Sunday, and United now consider the matter closed.
The club are said to understand the 19-year-old's actions were borne out of frustration after he started at the Vitality Stadium having only trained for the first time last week on Friday due to illness, and was then replaced by Amad Diallo at the interval.

Garnacho liked tweets from renowned United fan Mark Goldbridge who slammed both Ten Hag's decision to withdraw Garnacho and his post-match comments about him
It helped that Garnacho quickly 'unliked' the comment, and United also felt it was a very different situation to Jadon Sancho's social media post in September effectively branding Ten Hag a liar.
Sancho was forced to train on his own for four months and then loaned out to Borussia Dortmund in January after refusing to apologise.
Meanwhile, club sources have dismissed suggestions that Antony was left out of the squad at Bournemouth following a fall-out with Ten Hag over a lack of playing time.
Jadon Sancho effectively called Ten Hag a liar earlier this season, before he was loaned out to former club Borussia Dortmund back in January
It's understood the Brazil winger sustained an injury in training on Friday and did not travel with the rest of the squad to the South Coast.
However, Ten Hag is coming under increasing pressure after four games without a win as United prepare for Sunday's FA Cup semi-final against Coventry City at Wembley.
