Roma coach Rudi Garcia bemoans his team's failure to score a second as they were held 1-1 by a late CSKA Moscow equaliser.
The Giallorossi would have been in a very strong position to make it through to the next stage of the Champions League but Vassili Berezoutski's stoppage time effort means everything will be decided on the last day of the Group.
"When you don't score the second it's easy to concede like this," Garcia said.
"We should have closed the game earlier, it's a shame, there were only a few seconds left. Whatever happens in Manchester we have to win the game to qualify.
"We struggled in the second half but we defended well and we created chances with Ljajic and Nainggolan. A draw away from home is not bad but we leave with a lot of regrets.
"I repeat, I am very disappointed for how the draw was achieved, also because we would have been closer to the next round.
"Many thought we were going to be guests [in the group] when the draw was made but qualification is still an opportunity and we'll fight for it in our last game."
