Erling Haaland spotted helping out the referee in Manchester City's win over FC Copenhagen

Manchester City striker Erling Haaland is finding things so easy at the moment that he even had time to help out the referee during Wednesday's Champions League clash with FC Copenhagen.

Haaland, 22, scored a brace as City ran out 5-0 winners at the Etihad to maintain their 100 per cent record in the competition this season.

The Norway international has now scored an incredible 19 goals in just 12 games since joining City from Borussia Dortmund.

And it took him just seven minutes to open the scoring against Copenhagen.

He collected the ball inside the box before firing an unstoppable finish past visiting goalkeeper Kamil Grabara with his weaker right foot.

As City pushed for a second goal, eagle-eyed fans spotted a moment involving Haaland and referee Donatas Rumsas which highlighted the striker's fitness and eagerness to score.

During a City attack, Lithuanian official Rumsas dropped his vanishing foam - used for marking out free-kicks.

After a Copenhagen player kicked the canister containing the foam, Haaland picked it up and sprinted over to the referee – throwing it to him as City launched another attack.

Haaland then turned and sprinted back into the box, desperate to get another goal.

"Did anybody see Haaland run towards box, run back, pick something up for the referee, run after ref, give it him back then dart into box to try get on end of a cross!?? The guys absolutely unbelievable," wrote one fan on Twitter.

While another added: "Haaland is even taking time to help the referee."

While Haaland failed to receive the ball immediately after the incident, he would not have to wait long for another opportunity to score.

Just a minute later, he got his second of the match when Grabara spilled a shot into his path inside the six-yard box.

The goal prompted a hilarious reaction from City boss Pep Guardiola, who somehow seemed shocked by the Norwegian's second of the match.

It is hard to see why. Haaland has already scored three hat-tricks for City but would be denied the chance of a fourth, with Guardiola substituting him at half-time.

But it would not prevent the home side from claiming a convincing victory, with a Davit Khocholava own goal and second-half goals from Riyad Mahrez and Julian Alvarez sealing the win.

City have now won all three of their matches in the Champions League this season and sit top of their group.

They return to Premier League action against Southampton at the Etihad on Saturday before travelling to face Copenhagen in the reverse fixture in Denmark on Tuesday.
