The Argentine head coach is looking for new employers after Tottenham Hotspur surprisingly parted company with Pochettino last week.
The 47-year-old led Tottenham to four successive top-four finishes and a Champions League final during his five seasons in charge at the north London side.
However, Pochettino paid the price for a disappointing start to the Premier League season as Spurs appointed Jose Mourinho as his replacement.
Arsenal boss Unai Emery is coming under pressure following the Gunners’ five-game winless run in the Premier League, while Manchester United have been regularly linked with Pochettino since David Moyes’ axing in 2014.
Former Scotland striker McCoist explained why Pochettino should snub Manchester United in favour of taking over the reins at Arsenal if the opportunity arises.
Asked whether Pochettino would be better suited to Arsenal than Manchester United, McCoist told Sky Sports’ The Debate: “Yeah, I think so.
“I definitely think [a young team will be better for Pochettino]. If you’re asking me, I think he’d suit Arsenal’s squad more than he’d suit Manchester United’s squad.
“There are a group of players at Arsenal he could work with immediately. Manchester United is a far bigger job, by that I mean longer term, more of a rebuild.
“I think there are, at this moment in time, probably more players to work with at Arsenal. Manchester United fans might not agree with that.
“I do think Emery is vulnerable. I think he’s probably the most vulnerable [manager in the Premier League].”
Arsenal drew 2-2 with relegation candidates Southampton on Saturday after Alexandre Lacazette netted a late equaliser for the home side.
The Gunners are already nine points behind fourth-placed Chelsea FC in the race to secure a Champions League spot this term.
Emery took over the reins from Arsenal from Arsene Wenger in 2018 following his successful stint in charge of Paris Saint-Germain.
Arsenal haven’t won the Premier League title since 2004.
