Brescia president Gino Corioni has turned on coach Beppe Iachini.
The Rondinelle were defeated 1-0 by Udinese in a very unlucky result, having dominated the match.
"Iachini is an excellent Coach and I want to point that out from the start, but he needs to wake up when it comes to substitutions," said the patron.
"We attacked Udinese for the entire game, the pitch was in poor condition and some of the players were tired.
"Yet we finished with the same XI that started. The first substitution came at the 94th minute when I expected to see a change at half-time.
"Even in the third division you make three substitutions. In that respect, Iachini really does have to wake up."
