What a way to make a first impression.

Riccardo Calafiori, in his first start for Arsenal since joining the club in the summer, scored a sensational equalizer against title rivals Manchester City on Sunday. He curled home a beautiful left-footed effort in the 22nd minute to cancel out Erling Haaland's early opener at the Etihad.

Pep Guardiola and the Manchester City players were furious after the goal, which started with an Arsenal free-kick. They claimed Kyle Walker wasn't given enough time to get back into position after a discussion with referee Michael Oliver, but the goal was allowed to stand.

The tally helped Arsenal turn the tide in the match, as Gabriel scored from a corner kick in first-half stoppage time to give the Gunners the lead.

But Manchester City, playing with a man advantage for the entire second half after Leandro Trossard's red card, eventually scored an equalizer in the 98th minute to cap a wild affair at two apiece.
