"It is a really important game for Liverpool," said Vieira. "They can't lose the game - that would make it really difficult for them to come back.
"Now our confidence will be really high going into the game because this was a fantastic result away from home.
"For me Liverpool are still one of our biggest rivals. They have worked hard over the last few years to bring in some really good players and have the team to win the title. But we want to win it."
