He said: "We played a really complete game. It is always difficult to play against Brighton. You have to show composure. We were dangerous in transition and played the spaces really well."
On Unal, he said: "I was very happy, he has been pushing a lot. It has been a difficult situation for him because it is difficult to take minutes from Dom Solanke but we decided to play two up front tonight. I am happy because he scored a really, really nice goal in the second half.
"Yeah, we told him yesterday that it was going to be made permanent. We are very happy, especially with his attitude and how he is integrating on and off the pitch. It is a very good signing for us."
On a record points total, Iraola added: "We are really, really happy. The players deserve these points. They have performed really well. Even when we weren't getting points at the start of the season they were pushing and playing well. Now we want more points and to continue."
