Arteta spoke to BBC Radio 5 Live after Arsenal's 1-0 victory at the London Stadium, reflecting on a week that took in the Champions League semi-final win over Atlético Madrid, a Premier League trip to West Ham United and an injury crisis that forced multiple changes during the match itself.
"It has been a hell of a week — a rollercoaster of a week, with everything we have had to play for and all of the emotions in those games."
Arsenal lost Ben White to injury in the first half and Riccardo Calafiori at half-time, forcing a formation change and multiple substitutions that reshaped the match before the winner arrived.
"I said to the boys that we are going to go for it, so be ready. We are not going to wait for an action and we throw everything that we had on the bench for those players to make a difference. Martin Ødegaard came in and did an unbelievable action to pass the ball to Leo Trossard."
When Wilson's header crossed the line in stoppage time, Arteta described the moments that followed as agonising but ultimately correct.
"With a minute left they scored the goal and then the referee and VAR decided to have a look. It was a massive call but it was clearly the right call. My first instinct was foul — but then the time goes by, the referee is waiting for the VAR decision. When you look at it, the contact affects the way he lifts his hands, the way he catches the ball — it is almost on his throat."
He connected the decision to a season-long argument he has been making about officiating consistency.
"I've been asking for consistency all season when I have to be critical about it. Day one they said this was going to be a foul, and thank God — massive decision, especially when two teams are fighting for such big things."
On the title, Arteta turned the focus forward with characteristic discipline.
"Now we leave and enjoy what we have done today, because it has been an incredible week. Those players — the way they are standing in front of the opportunity and showing resilience — is remarkable. Recover a little bit and start to prepare for Burnley."
Arsenal are two wins from a first Premier League title since 2004.
