Roma lost the match 1-0 after a goal by United striker Wayne Rooney.
“It is tough and we feel rather bitter, as we played well and I think the draw was the very least we deserved,” he said.
“The next matches will be decisive and the fact we lost 1-0 at Old Trafford after a great performance was entirely acceptable. It just feels like a shame we were unable to get the points, especially after such a horrible result as the 4-1 to Inter on Saturday.”
