Felipe Melo has hit out at the critics of Fiorentina coach Cesare Prandelli.

"People are a bit stupid, because Prandelli has been doing incredibly well at Fiorentina for four years," snapped the Brazilian.

"After one bad game they point the finger. These people ought to use their heads a bit more. When the fans love their team, they should not be so critical after one bad game in four years.

"When a side qualifies for the Champions League, then gets attacked for one match, that is stupid, it's not love."
