Robert Pires went down to celebrate with the Chilean after the game.
Arsenal were comfortable winners today, defeating Stoke City 3-0 at The Emirates Stadium.
But there was little doubt who the star of the show was. Alexis Sanchez was superb for Arsenal throughout, playing a major role in all three goals.
His delivery set up Laurent Koscielny for the opener. He then scored the second after beating Asmir Begovic at the near post. He then made it three in the second-half with a free-kick that deceived the Bosnian, who should have done better with a squirming shot.
His performances are fast making him a massive favourite at The Emirates and he is surely on the path to become an Arsenal legend.
Of course today there was a pair of Arsenal legends in attendance.
French pair Thierry Henry and Robert Pires were both in attendance for the game, watching their beloved Arsenal take on The Potters.
And Robert was happy to get down into the dressing room after the game to celebrate with the match-winner, along with his son Theo also enjoying the moment...
