Everton swept aside Chelsea 3-0 on the night.
Asked how Everton managed to produce such a performance, Gueye revealed: “Because we followed the advice from the staff and the manager gave us confidence.
“He (David Moyes) said to us before the game, 'We really need to start playing like home today,' and I think the last game we did here gave us more confidence.
"We went on the pitch and we played as a team. We defend like a team, and that is what we need. We try to bring the club where the club deserves to be.
“The last year was not really good for the team, but now we start going forward, and that is what Everton needs."
He added: “Great game. We really played good as a team. We stayed calm with the ball, and we defended very well and we needed this win at home because our fans were behind us.
“They pushed us to win this game, and 3-0 without conceding a goal is very good for us and for the team. We just need to keep going in this way because
“(Playing at the) new stadium, it was not going well the last few games, but the last game we won, and we won again, so hopefully we continue like that.
“I think everyone enjoyed the way we play and everyone will enjoy this victory, and hopefully the next game we will win again.”
