The Gunners boss has come under increasing pressure from the club’s supporters this term as the Gunners have failed to land the league title in a season where all the so-called big sides have faltered.
Banners from the crowd have been present at matches asking for Wenger to step down, even in victory.
But Allardyce warns Arsenal that there is no guarantee of finding somebody better, not least now that a number of high-profile managers are contracted or promised elsewhere.
”I think it would be very dangerous to change Arsene Wenger. Who’s available and who do you get?” Allardyce asked when quizzed on the matter by the Mirror.
“Would they be brave enough to get another unknown, like Arsene was when he first went there? I think the game has changed so much that it would be a huge risk for Arsenal.’’
Arsenal have become a club so ingrained by Wenger’s style that a potential replacement may face a difficult task in stamping his own identity on the North London side.
Atletico Madrid boss Diego Simeone has often been seen as a potential candidate, yet his style is in stark contrast to Wenger and as such the Argentine would need to perform a squad overhaul.
While Arsenal have not won the Premier League title in 12 years, changing managers would not guarantee a change in fortunes with Manchester United an example of how a club can immediately struggle.
