The Orlando City defender's switch to MLS has given him the chance to play alongside the Brazil superstar.
St Ledger, 30, had failed an initial MLS audition during preseason when he left Eastern Conference champions D.C. United following an unsuccessful trial stint, before Orlando granted him a second chance for a career in the States earlier this month.
Joining ahead of their inaugural campaign, the Republic of Ireland international had to settle for a spot on the bench for their historic home opener against fellow expansion side New York City FC, but made his debut the following week in a 1-0 win at the Houston Dynamo in place of the suspended Aurelien Collin.
Despite a strong performance, he was back among the substitutes during last weekend’s 1-0 defeat to the Vancouver Whitecaps but the centre-back insists his backup role hasn’t at all dampened his start to life with the Florida-based outfit.
And, of course, part of that is down to getting the chance to both train and line up alongside a world class talent like Kaka.
“It’s not something I ever thought would’ve happened to be honest, I’ve played against him before but to play with him is something I will always be able to look back on,” he said.
“I wanted a change and when the opportunity came up to train with Orlando I jumped at the chance. I believe this is a club which has a really bright future.”
St Ledger has seen injuries hamper his career in recent seasons, with a reoccurring groin problem limiting him to just two appearances for Leicester City last term.
Released in the summer following the club’s promotion to the Premier League, the 37-times capped stopper struggled to find a new club until joining Ipswich Town on a short-deal in November but failed to feature during his one month at Portman Road.
He had harboured long-running ambitions of experiencing MLS, though, and is now even more convinced that he made the right move after witnessing a crowd of 62,000 at their home opener.
“It was great to see so many fans there, the city really has got behind the club. And it was nice to get the draw which I thought we deserved,” he added.
“That calibre of player signing will only make the profile of the league grow, especially as Sky Sports are on board too.”
