The Sheffield Wednesday playmaker was magnificent at the weekend.
“We decided on Tuesday that we would not be signing Forestieri, it was clear he didn’t have the right mentality needed to come to Leeds.
“I want players to show a hunger and desire to come here – but he did not."
Those words have come back to haunt Cellino.
Forestieri has been a star for Wednesday this season and at the weekend shot down Leeds in the Championship.
He assisted Gary Hooper for goal number one whilst it was his powerful drive, spilled by Leeds goalie Marco Silvestri, that saw Hooper bag the second in a 2-0 triumph.
"I think he will (prove a point today).
"When you read that someone has said something like that about you you'll try and shove it down their throat.
"He's enjoying his football enough and these people, these Sheffield Wednesday supporters, not many people will give you a sweet and make you feel welcome here and that boy is at home.
"You need to feel wanted and I think it is a joy to see him play at the moment."
He was prophetically correct as Forestieri tore into Leeds at will.
Right now Leeds boss Steve Evans is said to want a number 10, to link play between the attack and midfield. Forestieri could have been that man but he is instead doing that job for Wednesday - who look like forging a genuine promotion challenge this season.
