Fiorentina supremo Andrea Della Valle was left ruing referee Tom Henning Ovrebo after their Champions League elimination by Bayern Munich.
The Germans lost 3-2 on the night, but qualified on the away goals rule, 4-4 on aggregate. This was after Ovrebo and his linesman allowed a Miroslav Klose strike that was several yards offside in the first leg.
"It's a shame, as we showed how you play football. When the draw came out their players said they'd win 5-0, but instead we go out with a victory and the complicity of Ovrebo," snapped Della Valle.
"Winning 3-2 and not thinking back to the first leg is impossible, the mind will wander back there and the fans have to express their frustration."
He added: "We have our heads held high and the fans should be proud of this team, as it played great football and was more than equal to Bayern.
"It may not be worth anything, but it's good for morale, at least. I can't believe such a great squad is in 10th place in Serie A.
"It's tough to get back into the Champions League places, as we are a bit out of it by now, but there is the Europa League and the Coppa Italia. We'll see."
