After being denied twice in spectacular fashion by Porto goalkeeper Diogo Costa in the first 45 minutes, Haaland could not be stopped after the interval, nodding in from a curling Fernández cross.
Our talisman grabbed a memorable second in stoppage time, leapfrogging Tommy Johnson into third on our list of all-time leading scorers with 167 goals and levelling Sergio Aguero’s Champions League tally at City with 35 strikes for the Blues in the competition.

Deadline day signing Fernández had plenty of positive words for his new teammate after another matchwinning display.
“Haaland is an animal, a beast,” he said in an interview after the game. “Every time I’m on the pitch I will look for him.

“Hopefully I can give him more assists.
“Haaland is not just a great player but an amazing human being as well and he welcomed me here and has helped me.
“I’m so happy, they welcomed me from the first minute when I walked into the door. Not just brilliant players but they’re amazing human beings and they’ve all been so kind to me.
“The fans have been absolutely brilliant and it is a new step in my career. I’m so excited to get going.”
The Argentine midfielder thrived under the guidance of Enzo Maresca during their spells with Chelsea and Fernández is eager to pay back the new City boss with displays on the pitch.
“I’m so happy that Maresca did all he could to make this move possible,” he continued. “I know him so well from Chelsea.”
“I’m so grateful. I will give 100% in every training session and in every match to repay him.”
