Roared on by a buoyant Selhurst crowd, the Eagles were on top in a first-half in which Jean-Philippe Mateta was denied by visiting goalkeeper Alisson and later hit the bar, and several other Palace players came close to opening the scoring.
Liverpool turned the tide marginally in the second-half, but Vieira was equally pleased with the manner in which his players stood up to that challenge.
The manager surmised: “I think it was a good game from our side. We played with a lot of intensity and discipline.
“ We started the game really well. In the first-half we had those opportunities which we didn’t take in the end, and in the second-half, they had a really good spell in the first 20 minutes when it was really difficult for us, but we managed to not concede a goal and that was important for us to deal with the difficult period.
“After that, I think we finished the game in a better way.”
