Leonardo has slammed AC Milan and Inter.
The Brazilian worked with both clubs.
“For me, Inter's players aren't among the best players in the world, none of them are in the top 10," he told Sky Sport Italia.
“Unfortunately it's this: you can't say certain players [of theirs] are from Barcelona or Manchester United.
“At present, Milan are out of the Champions League. The best players aren't there.
“It's a market problem, but there they have just scraps from other [clubs]."
