Former Rangers player Fernando Ricksen has admitted responsibility for his dramatic exit from Ibrox.
But the Zenit St Petersburg defender insists he has nothing to prove to his old club when he lines up against them in Wednesday's Uefa Cup final.
The Dutchman was sent home from a pre-season tour in July 2006 and then treated in the Sporting Chance Clinic.
"I wasn't disappointed in the club for the way my time ended there," said the 31-year-old. "It was my own fault."
Then Rangers manager Paul Le Guen sent Ricksen home following an incident on a flight to South Africa.
And, after subsequent treatment, former Rangers manager Dick Advocaat ended his controversial spell in Glasgow by taking him to Russia.
"I have nothing to prove. What should I have to prove to Rangers or their fans?"
"I wasn't living life in the right way and I can't blame Rangers or their fans," said Ricksen.
"Look, it's not important that I used to play for Rangers. That has nothing to do with this final.
"I am a Zenit player and happy to be here. I want to bring this trophy back to Russia.
"I have nothing to prove. What should I have to prove to Rangers or their fans?
"I went away and left that part behind me, so I don't have any texts or contact with people at Rangers."
Ricksen is unsure of a starting place in the City of Manchester Stadium after missing the second leg of the semi-final win over Bayern Munich through suspension.

But he guaranteed himself a hot reception by repeating his swipe at the defensive tactics of Rangers, which have seen them concede just two goals in the competition.
Ricksen, who was jeered during a 4-1 friendly win for Zenit at Ibrox in August 2006 after a heavy challenge that injured Chris Burke, picked up on Barcelona midfielder Lionel Messi's critique.
"The biggest difference with Rangers is that, when I was there, they played football," he said.
"I don't know what they play now - I think it is called anti-football."
