Milan salvaged a point at Palermo on Tuesday after going 2-0 down, but President Silvio Berlusconi was reportedly left fuming at boss Massimiliano Allegri.
According to the Gazzetta dello Sport, Berlusconi phoned Vice-President Adriano Galliani after the game after being perplexed by the tactical tinkering of the Coach.
The Diavolo started the Stadio Barbera tie with a 3-4-3, but changed to a 3-5-2 and a 4-2-4 as they grabbed a 2-2 draw.
Galliani last night again confirmed that boss Allegri would remain in his place. Milan face Chievo this weekend.
