Roma coach Jose Mourinho was left frustrated after defeat to Atalanta.

La Dea defender Giorgio Scalvini struck the winner on the day.

Mourinho said, “It went badly because we lost a game that we should've won easily, considering the way we played.

“If we can imagine this domination we had in the final third, with many chances created, we can speculate that with Paulo on the field it might've been different.

“Nonetheless, those who played did well enough to win the game, easily, but unfortunately we did not score and that is why we lost.

“It is not pleasant to leave empty-handed, but it was a good performance, good spirit. We didn't dominate Monza or Cremonese here for 90 minutes the way we did Atalanta."

Mourinho was sent off for dissent and did not hold back on criticism towards referee Daniele Chiffi.

“There was a very clear penalty. I asked the referee afterwards why, and asked him to be clear with me that it was because Zaniolo did not go down. So therefore I have to change my advice to my players, I have to tell them don't try to stay on your feet, don't play the ball, be a clown the way many who dive like they're in a swimming pool do in this league, because that is evidently how you get penalties."

Did Chiffi confirm that?

“He was not clear with me."
