Hungary coach Marco Rossi was surprised by Inter Milan's defeat to Atletico Madrid Champions League.
Rossi says they were flat for the round of 16 second-leg.
He told Tuttosport: "Who plays better in Serie A? Inter, without a shadow of a doubt.
"I was amazed by the attitude in Madrid, I think they did something wrong from a mental point of view, at San Siro they had massacred the colchoneros.
"The Nerazzurri are dominating the championship. Inzaghi has found the best system for the players he has at his disposal."
