The Ballon d'Or nominees were more than happy to hold the famous hooped jersey, but not as happy as they will be at the prospect of running riot against Neil Lennon's side
It’s an image Celtic fans could barely even dream about: Lionel Messi and Andres Iniesta holding aloft the hooped Jersey. Oh, and Xavi there too!
Has Henrik Larsson been extolling the virtues of Glasgow to his former team-mates? Does Iniesta long to face clubs as steeped in history as Ross County? Is the Ballon d'Or winner hooked on deep-fried Mars bars?
Sadly not Celtic fans, unfortunately Messi & co. will not be strutting their stuff in green and white any time soon, barring a bizarre away kit next season. Nor is this a case of preemptive, Andre Santos-style shirt swapping.
The trio actually snuck past Tito Vilanova and out of training before stumbling upon Celtic's 125th anniversary celebrations. They posed for a cheeky snap before hitting the streets of Glasgow. Possibly.
But fear not, there will be plenty of opportunity to see the Catalan club's three amigos in the Champions League Group G clash, where an injury-hit Celtic side will be looking to avenge their stoppage time heartbreak at the Camp Nou.
