Just when it looked like being one of those afternoons for Manchester City, Erling Haaland stepped up from the spot. Goal No 28 inevitably followed. Over to you, Arsenal.
The celebrations at full time told you the importance of this result. The way Pep Guardiola was embracing his players. The way Haaland was beating his chest. The punches into the air. The hugs.
City had scuppered so many chances to score at Selhurst Park that Guardiola feared the worst. This was their last Premier League game until after the international break, by which time Arsenal could have opened up an uncomfortable lead at the top of the table.
