The midfielder produced two assists as Palace won despite finishing with nine men.
"You can talk about tactics," Eze told Premier League Productions. "But I think today it was mainly it was the heart and the desire to keep going, keep pushing and keep the mentality to stay strong (that secured the victory)
"The boys did that today, which was important. We did everything we needed to do. The boys who came off the bench as well, they put in an incredible shift. And again, we need everyone to push on throughout this season.
"We know what it means. We know what it means to the fans."
Eze added, "We're confident, we believe in ourselves.
"We trust that we can win every single game, so it's about putting in performances on the day.
"I'm sure that if we do that, we've got a good chance."
