The victory sees Pep Guardiola‘s men leapfrog the Gunners into top spot in the league table on goal difference.
Kevin de Bruyne struck the opener shortly before the half-hour mark, before Bukayo Saka levelled from the penalty spot shortly before the interval.
Jack Grealish and Haaland found the net within ten second-half minutes to secure the three points and our number nine was delighted with the dogged, determined and gritty display at the Emirates Stadium.
“We made small adjustments in the half time from Pep, we’re good quality players and we have to get it out every single player, that’s exactly what we did today,” he said.
“For me we have to play a little more like this sometimes, that’s exactly what we did today. I’m so proud today, I’m so proud of every single guy here, I’m so happy to be here.
“Of course, we can all agree they have been the best team this season, so to come here and play is not easy.
“But we played an amazing game and got three really important points and yeah, we’re in it again.”
The Norwegian, who claimed his 26th Premier League goal of the season under the floodlights by sweeping into the corner from De Bruyne‘s cutback, is hungry for more goals and is eager for the team to go on a winning run after this crucial victory.
“That’s my life [goals]. It’s already gone 20 minutes since I got my last goal, I’m already on it again, I have to keep working. I’ll do my best.
“It was so positive [at full-time]. There were happy celebrations right after the game. I’m so happy, I don’t know, I’m just so happy with everything.
