Former Germany goalkeeper Lehmann, who played for Arsenal between 2003 and 2008 and was part of their Invincibles squad, pointed out the key difference between the current squad and the history-making one helmed by Arsene Wenger, as he told The Daily Mail: "They're very different to us (Invincibles) in their approach - much more cautious and slower with the ball. Physically, they run a lot more and have more high-intensity runs but they don't play faster than us because we were a one-touch team.
"They all take three, four touches at a time. And if you're too cautious in football, you can't win trophies. Most of the time, the bravest teams win the league. I would love them to win the title but that has cost them in certain games. It's 20 years since we won the league and I hope Arsenal win but it's not in their own hands anymore and that's a weakness."
The former shot-stopper is also disappointed with how Arsenal bowed out of Europe.
"I was very disappointed with how they lost to Bayern Munich in the Champions League," he said.
"Afterwards, they showed a great reaction beating Chelsea and Tottenham. But to be a big club, you have to win trophies. He's (Mikel Arteta's) done a good job but unfortunately, you're talking to a guy who loves Arsenal, wants them to win and not just to be up there."
