It marked a first win in the Premier League since December, though leaves Spurs still in the Premier League's bottom three.
De Zerbi said afterwards: "Yeah, I think in the first half, in the first 30-35 minutes, we played well. We didn't create big chances to score, but anyway we had total control of the game.
"And then, I don't know, the pressure, maybe not winning any games in 2026, maybe this pressure, maybe because we played against Wolverhampton already relegated. We lost distances, we lost order on the pitch. Every one of us wanted to go one-to-one.
"But anyway, I'm happy for the result. I hope this result can change something in our head, in our mentality. And for the other results, it's already very tough to win a game for us. If we put our heads on the other teams, it becomes too tough for me."
On the injuries to Xavi Simons and Dominic Solanke, De Zerbi also said: "For Xavi it is a problem of his knee.
"We go to see in the next days. Monday or Tuesday. For Solanke it is not a big problem. I don’t know how many games we lose him but I would like to know the situation with Xavi because the knee is always different than the muscular injury."
