With Haaland’s goal settling the match, United were unsurprisingly disappointed by the decision.
“I think it was offside,” said Martinez. “And what I can’t understand is the rules. I want to be calm now, I want to control myself.
“It’s so hard because you lose a derby, you lose three points at home, and every season they’re [referees] coming to our club, they explain for one hour the rules, and they look so confident with that, and then after [there are] five or six people doing these kind of mistakes in the Premier League – it’s unacceptable.
“It’s the best league in the world, you have the best teams in the world, the best players in the world, and now we have to go home with this injustice.”
United boss Carrick also expressed his confusion.
“We put things in place in the game now, we have people in offices with all the screens for this decision,” he said.
“It’s more worrying about if that’s the interpretation of football now. If that’s the interpretation of not interfering in the game now, that’s really worrying for me. It’s a staggering explanation.
“The decision isn’t going to change the season, but it’s had a major impact on the game.”
Wayne Rooney, part of the BBC’s MOTD2 team, said: “Surely it’s offside. Martinez is impacted by Fernandez’s movement, and he is offside.”
Gary Neville said on Sky Sports: “I think we’ll see some sort of apology from the referee’s association, there’s no doubt Fernandez is playing that ball and is trying to put off Martinez. I think it’s one they’ll recognising they got wrong.”
Micah Richards added: “I think it’s been a bad day for referees. They got the Foden decision wrong and the Fernandez decision wrong. I think they got it so wrong but I don’t think it takes anything away from City’s performance.”
Meanwhile, City boss Maresca said: “I think it was onside clearly so it’s good.”
