The likes of Thierry Henry, Patrick Vieira and Dennis Bergkamp were instrumental as Wenger’s men secured their place in the history books, although they could soon be joined by two of Europe’s elite clubs.
PSG and Bayern sit at the top of their respective leagues and are yet to taste defeat, with many pundits backing the pair to go far in this year’s Champions League.
Lehmann, who also enjoyed spells with Schalke and Borussia Dortmund, explained: “[PSG] have the means and the potential [to achieve that]. Given their economic power, I’d even say that they should do it.
“But I also see Bayern becoming champions by staying unbeaten, since they’ve been playing at an exceptional level for several months.”
Lehmann also revealed the secret behind Arsenal’s title-winning campaign in 2004, adding: “We played a quicker game than most of today’s teams – notably quicker than Arsenal’s team this season – because we had extremely fast players in attack.
“We were also lucky to never have any injured players. Thierry Henry, who was our leading player, was never out of action.”
