The Paraguayan international captain dealt assuredly with everything Arsenal threw at him to shut out a team who have already netted 36 league goals in just 12 games.
"The game was good, very important win today for us," he told safc.com. "There was a lot of passion and I am very happy for my team-mates and for the fans.
"This is a big win for us and every player played well. I want to play in every game. It is fantastic to play in the Stadium of Light. I am enjoying things here.
"Arsenal are a good team, but we played well and deserved the points."
