Emery has found himself under increasing pressure at The Emirates following his Arsenal side’s stuttering start to the season.
The Gunners were held to a 2-2 draw by Southampton in the Premier League at the weekend to leave them with just four wins from 13 games this season and well off the pace in the race for Champions League qualification.
Indeed, the north London side are currently eight points behind fourth-placed Chelsea FC in the race to secure a top-four finish this season.
Arsenal’s poor form this season has inevitably led to intense speculation about Emery’s future, and Pochettino is now available after the Argentine was sacked by Tottenham Hotspur last week.
Merson feels that Pochettino would be a perfect fit for Arsenal, but says that he feels the move is unlikely to actually happen.
Writing in his column for Sky Sports, Merson said: “Arsenal should go for Mauricio Pochettino. He’s not won anything, but he improved Tottenham over five years, tenfold.
“He’s a top manager and he is about at the moment.
“I know he managed at Tottenham, but George Graham had been at Arsenal when he went the other way. You’ve got to get past that sort of stuff.
“These top managers don’t come along too often, where you don’t even have to pay anything for them.
“Can I see it happening? No. Should it happen? Yes. But it won’t happen. The days of the rivalry between Arsenal and Tottenham are not what they were. When I was growing up, it was the big football match.”
Arsenal will return to Europa League action on Thursday night with a home clash against Eintracht Frankfurt.
They will then take on Norwich City away from home in the Premier League on Sunday afternoon as they look to get back to winning ways in the top flight.
