The Germany international has been in scintillating form for Arsenal so far this season after the £42.5m playmaker scored five goals and made 18 assists in 28 Premier League appearances.
Ozil has helped the north London side challenge for the Premier League title, although the Gunners are 11 points behind current leaders Leicester City.
Klopp worked with Borussia Dortmund’s highly-rated Marco Reus during his time in charge at the Westenfeldian – a player who has been linked with his current employers Liverpool.
The Reds manager explained what area of the game German playmakers Ozil, Reus and Andre Schurrle need to improve.
“Now [in Germany], we have so many unbelievably skilled players and not one of these offensive players can make a header. It’s like we forgot it,” Klopp told a Subway series.
“Tall players, like Schurrle, Ozil, Reus, they are all like six foot, a good size, for an offensive player.
“They were strikers and they thought ‘ah, okay, no header’, bam, ‘I need a little bit of space’, bam, position moves back.”
Ozil moved to Arsenal from La Liga giants Real Madrid in 2013 in a £42.5m club-record signing.
Arsenal ended a three-game winless run in the Premier League thanks to Saturday’s 2-0 victory over Everton at Goodison Park.
