Lucas Leiva says Lazio's players were left frustrated after defeat to Roma.

Lazio lost the Roman derby 2-1 win.

“It's certainly not a good result for us, but I think it was a balanced game decided by two incidents," Brazilian Lucas told Sky Sport Italia.

“The goals were scored thanks to our errors and made everything more difficult. We must try to do better and not repeat the same mistakes."

This result ends a run of nine consecutive victories in all competition for the Aquile.

“I hope this defeat isn't given too much resonance. It can't cancel out all the good work we've done so far, as we must continue working and learn from these setbacks."
