Atalanta coach Gian Piero Gasperini took aim at Jose Mourinho after Sunday's draw with Roma.

Mourinho was sent off during the clash and later refused to speak to the press in protest.

In response, Gasperini declared: "Mourinho is often sent off, every 2-3 games. For me, refereeing this type of match is difficult, perhaps we can complain more than Roma but I have a hard time complaining about (Gianluca) Aureliano, he refereed in a difficult context.

"There was the episode of the penalty, the goal disallowed for (Gianluca) Scamacca where there would be a lot to say, then there are warnings that are difficult to comment on like that of (Davide) Zappacosta.

"I think it's impossible to referee this type of match calmly, the conditions aren't there."
