The Red Devils concluded their US tour with a match against the Bundesliga giants.

Erik ten Hag gave the 19-year-old a stern talking to

Forson, 19, was part of a largely second-string first-half XI fielded by boss Erik ten Hag.

He played well to start the game before having a forgettable moment.

The winger kicked out at Julian Ryerson after attempting to tackle Karim Adeyemi.

Ryerson, a defender, and Adeyemi, a striker, both reacted angrily; Forson engaged Adeyemi head-on.

Adeyemi and Forson were both arrested as a result of the encounter, which also saw Forson swing an arm.

Ten Hag was furious on the sideline, and immediately sent Antony on to replace Forson.

The youngster was visibly gutted as he left the pitch, and was consoled by experienced heads Christian Eriksen and Scott McTominay.

Ten Hag, 53, gave Forson a lengthy talking to when he reached the touchline.And after the match, the Dutchman warned: “When there is a VAR, he gets sent off.

“He played a good game and the opponent gets annoyed with him, so that is a learning curve but don’t take it into your own hands.

“You can’t be the judge, you have to play football, you have to beat your opponent, you have to net and that is the best way to react.”

United took the lead on 24 minutes courtesy of Diogo Dalot’s strike, but were pegged back by Donyell Malen’s double on the stroke of half-time.

Forson’s replacement Antony levelled on 52 minutes, before Youssoufa Moukoko bagged Dortmund’s winner on 71 minutes.

Following his side’s 3-2 defeat, Ten Hag blasted: “There are no excuses.

“We have to perform no matter what and then you have to be ruthless and win games because we are Man United and the fans are expecting from us wins.

“I said to the team, ‘I think it was a good tour but you want to finish with a good performance and you see only 60 minutes where I was pleased with but not with the goals we conceded because they were really poor.”
