Lacazette smashed the kick low into the corner and Arsenal preserved that 2-1 scoreline to the end. But this was a foul in any sport you care to name – ice hockey, karate, Shrove Tuesday midden-ball. Sánchez came barrelling right through his man all the same. Perhaps José Mourinho will continue to dispute the award of that match-winning penalty just after the hour, with the score 1-1, as Davinson Sánchez came storming back to intercept a long pass to Alex Lacazette.
