Borussia Dortmund coach Jurgen Klopp has insisted that Real Madrid were wrong to sell Mesut Ozil to Arsenal in the summer transfer window.
Klopp has suggested that perhaps Real president Florentino Perez needed the money after buying Gareth Bale for £84m.
"I do not care which player will play against us in the UEFA Champions League," Sky Sports News quotes Klopp as saying. "But Mesut is a football grenade. No-one really knows why he was sold. Maybe Real Madrid needed the money?
"Real Madrid chairman Florentino Perez wanted to have Gareth Bale, of course, and he paid £84m.
"Perez once even bought Hochtief [a German construction company]. Maybe he just doesn't know in the mornings what he is about to do with his money when the evening comes."
The fee to take Ozil to Arsenal was £42.5m.
