The temperature is rising ahead of tonight's derby between Fiorentina and Juventus. 

And now Sebastien Frey has decided to throw his two cents in, tweeting a message of encouragement to his former team, for which he played between 2005 and 2011.

"We're all with you boys for tonight's game.. Forza Viola!"

The problem, however, is that the former Fiorentina mainstay also added the picture below, fanning the flames of a rivalry that is already very intense. 

It is interesting to note that the former French international chose a picture made by the C.A.V. (Collettivo Autonomo Viola), a former Ultra group which disbanded in 2011.
