The former striker believes the England international would benefit from top-level competition as his spell at Etihad Stadium comes to an end.
Indeed, Pep Guardiola has signed Claudio Bravo as part of his Manchester City reshuffle after Hart made what will likely be his final appearance for the club in the victory over Steaua Bucharest on Wednesday.
The 29-year-old has been linked with a move to Sunderland and Torino over the weekend. But former Collymore believes a stunning witch to Emirates Stadium would suit Hart more.
"At 29, in goalkeeping terms, he is just coming into his peak years, so if he wants a future with England, he needs to bed himself into another club," wrote Collymore in his column for the Mirror.
"I know they have Petr Cech – who is 34 – but why not Arsenal? I’ve always felt Hart would benefit from top-level competition and I think he’d be an ideal keeper for the Gunners.
"I also think with his top-level experience he could do well at Liverpool too."
