In a see-sawing game, the Cherries saw a 2-0 lead hauled back by the visitors before Amine Adli struck a 95th minute winner.
Iraola told the Daily Echo afterwards: “I think it's probably the best goal to score, because I had just asked the fourth official 10 seconds before he told me no, the game is over.
“It's just this long throw.
“So when you score, you know it's okay, it's a win. And sometimes it has happened differently this season.
“We've conceded stoppage time goals, the other day against Brighton, the Burnley game. But when it happens to your side, it's a lovely moment to celebrate.”
On managing the game, Iraola was particularly pleased: “I think we are finding lately ways to get points or get wins a little bit in a different way.
“Normally we go full gas since the beginning, we try to keep the energy until the end.
“And now probably because we don't have the numbers, because we need to adapt a little bit, we are choosing a little bit more the moments when to go, when to stay a little bit deeper.
“Also thinking that we need to save a little bit of energy for the end of the game. And I think in a different way the team is finding ways to get points.
“After a very bad run, I think it's seven points from the last nine against Spurs, Brighton, Liverpool. It's a good amount for us in a moment that we really needed it.”
