The 36-year-old spent two years with the Scottish Championship side.
Carlos Bocanegra has admitted that Rangers' promotion back to the Scottish Premiership was tinged with a little sadness for him as he was not part of the team that was able to finish the journey back to the top flight, the Sunday Mail reports.
The retired defender spent two years with the Ibrox club - though most of his second year was spent on loan with Racing Santander before he departed permanently for Chivas - and was part of the side that was playing its football in the Premiership one year and the Third Division the next.
And after hearing that Mark Warburton's men had confirmed that they would be playing at the highest level next season following their 1-0 win over Dumbarton on Tuesday, Bocanegra conceded that he had some regret about how his time with the Light Blues came to a conclusion, but insisted that he loved his spell at Ibrox.
"On Tuesday, part of me was sad because I didn't come back and help finish the journey back to the top," he told the Mail.
"But because of the wages involved, it just wasn't going to work out. Honestly, I didn't want to leave.
"I wish I'd signed for Rangers a lot earlier in my career. If I'd had I could easily have spent five or 10 years there. That's how much I enjoyed it."
Although the former Fulham man's playing days are over, the 36-year-old remains involved in football as he is currently sporting director of Atlanta United, who will join MLS next year.
And if that spell proves successful, then perhaps the Gers' former skipper will be able to address the unfinished business he has with the club by returning in some capacity to help Warburton establish the side as heavyweights once again.
