New Manchester United goalkeeper Andre Onana showed he will bring more to Erik ten Hag’s team than ball-playing ability during a 3-2 defeat by Borussia Dortmund in Las Vegas.
The 27-year-old Cameroon keeper, who came on at half-time, has a reputation for letting rip at team-mates.
And he had a furious rant at Harry Maguire after a slack pass to Christian Eriksen gifted Dortmund a chance.
Onana denied Sebastian Haller then raced from his goal to berate Maguire.
The former United captain kept his counsel, which is more than could be said of fellow defender Brandon Williams, who got involved in a slanging match with Tom Heaton, who started in goal as United’s three-match tour of the United States ended in defeat in front of 50,857 at the Allegiant Stadium.
Williams had been responsible for Donyell Malen cancelling out Diogo Dalot’s excellent opening strike, but took exception to being blamed by Heaton for Dortmund’s second goal, barely a minute later, when Victor Lindelof gave the ball away.
Heaton seemed to suggest Williams had been too slow getting out and had played Malen onside. Williams evidently disagreed, making his feelings known in industrial terms.
Antony equalised for United but another defensive error, this time from Aaron Wan-Bissaka, who gifted Dortmund possession close to the penalty area, ended with Youssoufa Moukoko scoring the winner.
It was a sobering evening for 18-year-old Omari Forson. Given his fourth pre-season appearance, the Londoner had impressed until he got involved in a head-to-head confrontation with Karim Adeyemi.
Ten Hag was concerned enough about the situation to venture on to the pitch. Bruno Fernandes complained to the fourth official as Dortmund continued to niggle away at the young midfielder, whose concentration had evidently been affected.
Amad Diallo missed the game with a knee injury that still requires an assessment and the Ivory Coast winger was noticeably limping as he left the stadium.
It is anticipated 18-year-old midfielder Kobbie Mainoo will be out for an extended period with the ankle injury he sustained in the 2-0 defeat by Real Madrid in Houston on Wednesday.
