Rob Holding was slammed for dashing Arsenal's north London derby hopes thanks to a "stupid" red card.
The 26-year-old, who has enjoyed a period of good form in recent weeks while deputising for the injured Benjamin White, crashed into Tottenham Hotspur forward Heung-min Son in the 33rd minute and was shown a second yellow card by referee Paul Tierney.
Holding had picked up his first booking seven minutes earlier, bringing down Son again shortly after Harry Kane gave Spurs the lead from the penalty spot. It didn't take long for Spurs to capitalise on boasting the extra man in the crucial top-four clash, as Kane headed home his second goal of the game from a flicked-on corner.
