Steve McClaren’s men clicked into gear after losses to Leicester and Palace to beat the Reds 2-0 at St James Park.
We go into the game on a run of 14 unbeaten in the Premier League and with top spot secured in Europa League Group J with a win against Monaco on Thursday.
“Newcastle are coming from a big victory against Liverpool last week and I think they believe more than before,” said Mauricio.

“That victory gave them more confidence and it’s because of that we expect a tough game.
“Newcastle will come here very aggressive and try to win.
“We need to work hard, to have the same motivation and mentality, play to our philosophy and make sure we’re ready to compete.”
Asked if he felt teams were starting to step it up against us, Mauricio added: “I don’t know. I always try to focus on our team and how we can improve and we have a very tough game ahead.”
