The Sweden midfielder gears up to face his former club in a contest that the hosts just might fancy winning, with the Gunners enduring some indifferent Premier League form over recent weeks.
Sam Allardyce's side sit 18th in the Premier League table, one point shy of safety with a game in hand meaning that survival, for the moment, is very much in their own hands.
Home to Arsenal is arguably the toughest of Sunderland's five remaining fixtures and victory would certainly boost their survival prospects considerably, and Larsson urges the club's fans to make the Stadium of Light a cauldron on Sunday as they look for an upset.
“The Premier League has been upside-down and the teams you don’t expect to win are beating the top teams, so we fancy our chances but we also know we have to perform really well to make that happen," he told the club's official website.
“Arsenal are a very good team and on their day they can blow any opposition away, so let’s try and focus on ourselves as much as we can and put in a good performance.
“The fans have been brilliant throughout the season and I’m sure it will once again be a noisy place on Sunday, and that will give us a big lift.”
Few would doubt Allardyce's capacity to lift Sunderland out of the danger zone in the nick of time, especially after smashing Norwich, in 17th, 3-0 at Carrow Road last time out.
It was a big step in their pursuit of safety, and we may see another tomorrow.
