Roma veteran Aleksandar Kolarov offered no excuses after defeat to Bologna on Friday night.

Musa Barrow bagged a brace and assisted the opener for Riccardo Orsolini at the Stadio Olimpico, while Stefano Denswil got an own goal and Henrikh Mkhitaryan's late header set up a tense finale.

“We lost a game, Bologna deserved to win, that is all," Kolarov told Sky Sport Italia.

“Our 2020 has not started well, but these periods can happen during a season. All we can do is keep our heads down and work harder.

“We knew Bologna were tough to beat and dangerous on the counter-attack. Our pressing was not good enough and that left us flat-footed on the counter. Bologna absolutely deserved to win and we did not perform up to our standards today. We did better after the break, but it was not enough.

“There are many elements to the negative period, but as the oldest of the group, I stay close to my friends, we discussed it, know what we need to do and keep going forward."
