Fiorentina have blasted AC Milan over their move for Adem Ljajic.

Paolo Panerai took to Twitter on Saturday to attack Milan Vice-President Adriano Galliani for an approach that was "violating the rules."

"With regards to what was said yesterday by Paolo Panerai on the Ljajic issue, Fiorentina confirm our counsellor's comments were personal expressions," read the statement.

"Having said that, we consider Milan's offer to be unacceptable, certainly late and absolutely inopportune."
