Frequently taking part in Arsenal training sessions
has convinced the French World Cup winner that his former club can win
the Premier League title
Arsenal face north London rivals Tottenham on Sunday as they look to bounce back from Wednesday night's 5-1 mauling by Bayern Munich – a third defeat in four outings this season in Europe's top-tier competition.
It has been a different story domestically, with Wenger's team level on points with leaders Manchester City ahead of the home encounter with their near neighbours.
French World Cup-winner Pires lifted the Premier League trophy twice during a decorated spell at Arsenal – their last title coming in 2004, two years before his departure to Villarreal.
"Arsenal have started the season well," said Pires in an interview with the Guardian. "Actually, since the game against Man United [Arsenal's 3-0 win at Emirates Stadium last month] they are doing very well," he says.
