Atletico down Carrick's struggling Manchester United

Man United have made their worst domestic start in 40 years and this league phase defeat in the Spanish capital was another blow, with the team now winless in five games across all competitions. Man United defender Lisandro Martinez said the team's performance was "really poor" and suggested it was also a reflection of how the club is being run.

"It is annoying, disappointing coming here and I am not seeing my team trying to get an amazing result here, it's disappointing," he. Carrick handed Carlos Baleba his first start for the club since arriving from Brighton this summer, as well as pushing captain Bruno Fernandes out to the right side.

Atletico were without their skipper Koke, after the death of his mother, while coach Simeone selected Julian Alvarez from the off for the first time this season at the Metropolitano stadium, after he tried to force a departure this summer.

"As well as for the team, it was very important (to win) for Koke and all of his family, it's a very tough day for them, this victory is for them," said Barrios. "Getting the goal so soon helped us to manage the game later, I'm really happy for the win.

"Atletico fans ordered their supporters to "defend what we love" with a banner display before kick-off and the Rojiblancos were ahead after just 50 seconds. Alex Baena found a way in behind United's defence and cut the ball across for Barrios, with Ayden Heaven unable to keep the midfielder's shot from crossing the line.

Barrios held up six fingers to pay tribute to Koke. "It was really tough news for everyone and I said if I scored I would do that," added Barrios. Carrick had said it was important to get off to a fast start, but his team were unable to follow his instructions.

Bryan Mbuemo might have equalised for the visitors, nudging the ball through Cristian Romero's legs but firing just wide. Alejandro Grimaldo came inches away from extending Atletico's lead with a free-kick which hit the angle between post and crossbar.

The hosts thought they had a second when Johnny Cardoso finished neatly from the edge of the box before half-time but the goal was disallowed after a VAR review showed the ball had struck Marcos Llorente's hand during the build-up. Hitting the woodwork.

Alvarez, yet to score this season for Atletico, hit the post early in the second half. United rallied and Fernandes's lob drifted narrowly wide before the Portuguese playmaker hit the crossbar from the left of the box after a corner routine.

However the three-time European champions suffered a setback when defender Yoro was harshly dismissed after a VAR review for bringing down Canada striker Jonathan David as the last man.

It opened the door for Atletico to grab their second, with David foiled by goalkeeper Senne Lammens but London-born Nigeria international Lookman was on hand to tuck home the rebound after 79 minutes. Carrick withdrew playmaker Fernandes, looking ahead to the weekend visit to face rivals Leeds in the English top flight, where improvement is badly needed.

"It is very hard to say after a defeat that there is positives. We just have to work hard to keep working and keep trusting in our structure," United midfielder Youri Tielemans. "We have to keep working, keep trusting each other and be together on this.

"Atletico goalkeeper Jan Oblak saved from United substitute Matheus Cunha in the final stages but there was no way back for United. Simeone's side were able to claim their first points after an opening defeat at Liverpool.
