Roma outclassed their Europa League opponents 4-0 on the night.
Belotti was happy with his brace, stating: “In the second half we entered the field with the attitude to close the match and in 10 minutes we did so. In the first half we conceded something and we shouldn't have because we are Roma and we want to win this group.
"We must always go onto the pitch with the right attitude without doing anything wrong. The Europa League is as important as the championship, we must find the right balance to grow as a team and have the perfect attitude in every match until the end of the season.
"I know what I went through last year, it wasn't easy and throughout the season I never found myself in top form due to preparation and injuries, but I knew that in this season, having had an important retreat, the results would come."
