The Gunners came from a goal down to earn the three points against the Foxes after Danny Welbeck came off the bench to net the winner last Sunday.
The result could prove pivotal in the Premier League title race and moved Arsenal to within two points of top spot heading into the final 12 games of the season.
Alexis Sanchez tweeted this picture of himself celebrating with the likes of Mesut Ozil and his other team-mates after the game.
However, former Arsenal defender Keown was less than impressed by the social media post and urged the Gunners to focus on their performances on the pitch.
Keown wrote in his column for the Daily Mail: “As for Arsenal tweeting those pictures after beating Leicester, I haven’t got time for that.
“I think I’d only take my photo with team-mates if there was a trophy involved.
“It was telling that there no Petr Cech in that photograph – he knows what it’s like to be a winner and I’m sure there are plenty of photos of Cech in the dressing room at Chelsea but he’ll have a trophy in his hands.”
Arsenal are currently preparing for the first leg of their crunch Champions League clash with Barcelona on Tuesday night.
