It was a shocking way to end what has otherwise been an excellent first season back in the Championship for Pool, who finished 23 points clear of the bottom three.
The defeat - unsurprisingly - was Blackpool’s heaviest of the campaign and was the first time the Seasiders had shipped five goals since the final day of the 2015/16 season.
Posh were also the opponents on that day as they thrashed Pool 5-1 to confirm their relegation to League Two.
“Firstly I’d like to apologise to the fans,” Maxwell told The Gazette.
“I’ve been very public in talking about it all season that I genuinely believe our fans are absolutely fantastic and are the best fans I’ve played in front of during my career.
“The support they give us when we go a goal down, the support they give us home and away, the noise they make and after the game after being completely not at the races, the support they showed after the game, it was phenomenal.
“I’m one of the 11 on the pitch and as captain of this football club, which I’m completely honoured to be because it’s one of the highlights of my career, I have to say I’m really, really upset with the result, I’m really upset with everybody’s performance and it’s put a sour taste in my mouth for the six-week break.
“For me, who often dwells on performances, who is desperate to win every single game, every single training session, every single thing I participate in, it hurts me. It hurts me well and truly.
“All I can do is apologise for that, because it’s taken the shine off what has been a successful season which has laid the foundations for next year.
“There was no hiding place out there. Credit to them because they did play well, but it was made a lot easier for them because of our performance.
“That was the first time since I’ve been here that this has happened, so I can only apologise.”
