Benzema scored twice against Levante to help his side register a 3-2 win during their La Liga clash on September 14.
Tuchel also termed the Frenchman as 'top class' saying that Benzema has a lot of qualities.
"He's top class and very difficult to defend against because he doesn't only play as a number nine. He goes wide, he goes everywhere. He has a lot of quality and crosses well, he's good at headers... what more can I say?" he said.
PSG will compete against Real Madrid in Champions League on September 19.
