Erling Haaland scored twice to power Manchester City to a commanding 2-0 victory over Porto in their opening UEFA Champions League fixture — a result that arrived against the backdrop of a heated tunnel confrontation at halftime.

City's players returned from the interval with a point to prove, and Haaland delivered, netting a brace that settled any lingering uncertainty about the outcome. The Norwegian striker's contribution was clinical and decisive, giving Pep Guardiola's side a winning start to their European campaign.

The atmosphere surrounding the match was anything but routine. An altercation in the tunnel at the break added an edge to the second half, with both sets of players visibly fired up when they returned to the pitch. Manchester City, however, channelled that intensity into their football rather than friction.

Porto, playing at home, were unable to contain Haaland — a man who has made a habit of tormenting European opposition. The clean sheet underlined City's defensive solidity alongside their attacking firepower, rounding off a professional performance on the road in Portugal.

The victory sets Manchester City on a strong footing in the group stage, with Haaland once again demonstrating why he remains one of the most feared strikers in European football.
