'I was worried' - Wayne Rooney reveals major concern during Man Utd's scrappy win over Chelsea that would have seen more pressure mount on head coach Ruben Amorim

Amorim's side picked up a much-needed win on Saturday by beating Chelsea 2-1. The Blues suffered an early blow when goalkeeper Robert Sanchez was sent off after just four minutes, before goals Bruno Fernandes and Casemiro put the hosts in a commanding position. United looked set to cruise to victory but a red card for Casemiro and a late goal from Trevoh Chalobah meant Amorim's side ended up hanging on for a scrappy win.

Rooney has now shared his thoughts on the game and admitted he feared for the Red Devils after Chelsea went a man down. He told The Wayne Rooney Show on BBC Sport: "Do you know what? I thought even with 11 men, I thought they started the game really well and caused Chelsea problems. And then when Chelsea went to 10 men, I was worried! I was thinking, it's just like United now to go and lose the game. And then I think that would have brought a whole lot of more pressure on the manager. But I thought they played really well first half and then second half, it's silly, it's naive from Casemiro. As soon as he got his yellow card, I was watching it in the BBC studios with Danny Murphy and I said that I'd take him off. He's going to get sent off. You just knew what was going to happen and it could have cost us in the end."

Rooney also revealed how impressed he was with Manchester United's discipline after they had lost Casemiro. He added: "I think what I liked in the second half was the discipline from United, they defended well and kept the ball in front of them and Chelsea were poor. Chelsea were slow and moving the ball side to side but not really trying to penetrate. The only two crosses they put in the box is the one for the goal and one late on which caused another big chance but I think you have to praise Man United for in them conditions as well, they showed a lot of discipline and that's a huge win. Let’s just enjoy the three points!"

Casemiro's red card means he is the first Manchester United player to score and be sent off in the first half of a Premier League match, and the first overall in the competition since Emmanuel Adebayor for Spurs against Arsenal in November 2012.

Manchester United will be aiming to maintain their winning momentum when they return to action on Saturday against Brentford in the Premier League.
