MANCHESTER — Ruben Amorim warned Manchester United to stop making life so “complicated” for themselves after they eased the pressure on their beleaguered boss with a 2-1 win against Chelsea yesterday.

Fighting to avoid the sack after a woeful start to the season, Amorim received a welcome boost when Chelsea goalkeeper Robert Sanchez was sent off after just five minutes at Old Trafford.

Bruno Fernandes quickly put United ahead with his 100th goal for the club in all competitions in his 200th Premier League appearance.

Casemiro doubled United’s lead before the Brazil midfielder was dismissed for a second booking in first-half stoppage time.

Trevoh Chalobah’s late reply for Chelsea set up a tense finale, but United held on for just their second win in six matches in all competitions this term.

Having kicked off languishing just above the relegation zone, Amorim’s side climbed provisionally to ninth place, to give the Portuguese coach a little breathing space.

“It was really important. I think we deserved it, but we complicated our lives every time,” Amorim said.

“I think we started the game really well in terms of the aggression and to push the opponent and to show that we were there, even to bring our fans with us.

“Of course, the sending-off of the goalkeeper helped us a lot, but we were in control, we scored two goals. And with everything going well, we made things complicated with that sending-off.

“The second half I think we managed well, but, in the end, the last 15 minutes was tough for us. They scored a goal and then we suffered together and we managed to win.”

After such a torrid start to the season, Amorim was proud of the way United dug deep to secure just their second win in all competitions this term.

United failed to win successive Premier League games last season and Amorim challenged his players to end that barren run at Brentford next weekend.
