Fiorentina coach Cesare Prandelli admits Alberto Gilardino went against his instructions in converting his penalty in their 3-0 win over Genoa.
There was some tension on the field, as Gilardino and Stevan Jovetic bickered over who was to take the spotkick.
Prandelli said: "Gilardino is not the designated penalty-taker, so he made me a bit angry, but when Jovetic handed over the ball there was nothing more I could do."
