Manchester United showed their character by comprehensively beating Real Betis 4-1 in the Europa League four days on from their humiliating defeat at Liverpool.
Sunday's 7-0 collapse at their bitter rivals equalled the club's record competitive defeat and left manager Erik ten Hag calling for a response from an unacceptable loss that he labelled "unprofessional".
The United boss stuck with the same starting line-up that was annihilated at Anfield and the players repaid their manager's faith in a 4-1 victory against Betis in the first leg of their last-16 tie.
Marcus Rashford kept his cool to lash the hosts into an early lead as the snow fell at Old Trafford, only for Ayoze Perez to drill home a superb leveller against the run of play.
That moment gave hope to Manuel Pellegrini's side and David De Gea was breathing a sigh of relief just before the break after his terrible pass led to a Perez effort deflecting off the post.
But United returned strongly from half-time and Antony curled home a lovely left-footed strike before skipper Bruno Fernandes, who faced intense scrutiny for his Liverpool display, headed home.
Wout Weghorst, another criticised after Anfield, scored his first Old Trafford goal to wrap up a comfortable win that means Ten Hag's men head to Seville next Thursday with a three-goal cushion.
Rashford was pleased with how United won their Europa League clash after Sunday's debacle at Liverpool.
"It's always important to win the next fixture, and it's the only way for us to bounce back and continue the momentum we had before that game," the forward told BT Sport.
"So I'm pleased that we managed to win the game and were so positive in attack."
He added: "I thought that they defended in the box quite well in the first half and the second half it opened up a little bit more, as expected with the game being 1-1.
"We're pleased that we could win a game and start in the right way."
