Decorous is the word to describe Claude Puel's reaction to what was a grandstand finish manufactured by problematic refereeing.
Arsenal won this at the death, in the fourth minute of injury time, thanks to Santi Cazorla's penalty, but the real story was not of any relentless late barrage but Bobby Madley's blind spot in the build-up.
Laurent Koscielny lay inside the six-yard box after taking a whack to the head in a previous phase, Madley somehow deciding that play ought to continue.
