Former Arsenal youngster Bentley came off the bench to make his second debut for the Ewood Park outfit at the weekend as Rovers dumped the Gunners out of the FA Cup with a shock 1-0 victory.
Bentley, 28, proved to be a big hit at Blackburn first time around after joining from Arsenal in 2005.
He won the first of seven England caps in 2007, but left on a sour note after publicly agitating for a move to Spurs worth £17million pounds in October 2008, something he now admits was a mistake.
"I didn't do it the right way - I was a naive young man and made the wrong decision," said the midfielder.
"I thought I was making the right choice but you can't act like that.
"I apologise for the way I went about it because I love being here, I love playing for this club.
"I thank them for what they did for me while I was here and it's good to be back. Hopefully I can replay them by coming back and performing for them."
