The Portuguese winger admits that their performance was worthy of the victory, but conceded that gaining a draw from the fixture was sufficient reward
An 89th-minute equaliser from Anderlecht striker Dieumerci Mbokani snatched the victory away from Manuel Pellegrini's men, despite a double from the Portuguese winger.
Los Boquerones, playing in their first Champions League tournament, move into the knockout stages of the competition with an unbeaten record, and although the 32-year-old lamented conceding late, he was still delighted with the progress the team have made.
"We have done a great job here tonight," Duda told reporters.
"We are happy with the performance, it's just a shame about the final goal. The importing thing though, is that we got the point.
"Now we can move on and think about the next La Liga match."
