Junior Kroupi found an injury-time equaliser for the point from Elland Road.
Iraola told the Daily Echo: “I think when you score in the stoppage time and you recover one point that looked lost, I think you finish with better feelings probably than the draw we got against Newcastle the other day.
"I think four goals come from set pieces. And the game has been for me very, very physical. I think we struggled in the first aerial duels, and not only in set pieces, or only when they were playing direct with Calvert-Lewin.
“He was winning a lot of these first contacts. They have a very physical midfield. Sean Longstaff and Ampadu, Struijk. They are good winning these second balls.
“And the game was becoming quite physical. And normally we are a team that we are good in those scenarios and the more open for us the better.
“But I think the Leeds also have been very good there. They have been very good on the duels and fighting for the ball. You can see it's a team that has soul and it has been difficult for us.”
