Pep Guardiola's hilarious reaction to Erling Haaland's second goal against FC Copenhagen says it all

Erling Haaland shows no signs of slowing down after scoring another two goals for Manchester City in their Champions League win over FC Copenhagen.

The Norwegian striker has made a remarkable start to his career with City, already scoring three hat-tricks for his new side after joining from Borussia Dortmund.

He was handed another opportunity to impress on Wednesday as City hosted Copenhagen at the Etihad.

And it took Haaland just seven minutes to open the scoring, the Norway international firing an unstoppable finish past Copenhagen goalkeeper Kamil Grabara with his weaker right foot.

Later in the half, he grabbed his second – Haaland reacting quickest after Grabara had spilled a shot, leaving the striker with the easiest of finishes.

While Haaland wheeled away in celebration, the TV cameras managed to capture Pep Guardiola's reaction to the goal.

The City manager gestured in the direction of the striker with an astonished expression on his face.

City would go to score again in the first half through a Davit Khocholava own goal.

Mercifully for Copenhagen, Haaland was taken off at half-time by Guardiola, who no doubt has one eye on Saturday's Premier League match against Southampton.

But it would get worse for the visitors in the second half when Riyad Mahrez added another goal for the home side from the penalty spot.

Julian Alvarez also got his name on the scoresheet as the match finished 5-0 to City, who maintained their 100 per cent start in the Champions League this season.

Haaland's brace took him to 19 goals for the season in just 12 appearances.

He has now scored 28 goals in the Champions League, moving level with Manchester United legend Ryan Giggs and former Marseille, AC Milan and Bayern Munich forward Jean-Pierre Papin in the all-time list of top scorers in the competition.

Earlier this week, Guardiola hailed Haaland as the best young player in world football.

"At his age, no-one can compete with him, no-one," said Guardiola. "The numbers speak for themselves."

They certainly do.
