Celtic made it through their Europa League group into the knockout stages, and their reward is a last 32 clash with Italian giants Inter Milan.
The 2010 Champions League winners have struggled ever since the departure of Jose Mourinho almost five years ago, but still pose a tough test for Celtic, who will no doubt be looking to create a raucous atmosphere at Celtic Park when their more illustrious counterparts arrive in Glasgow in 2015.
Yet when the two sides meet, there could be a surprise reunion on the cards after it was reported in Italy that Inter will look to snap up one of Celtic's star players in January.
With 11 goals in 15 games, Guidetti has won the hearts of the Celtic faithful in just a matter of months, but is only on loan from Manchester City, meaning teams are lining up January moves to sign him permanently on the basis of his goals for Celtic.
Hull City and Marseille have already been linked with Guidetti, but Inter are now entering the race, with manager Roberto Mancini reportedly keen to reunite with the Swedish international having managed him at City.
The prospect of joining a club as big as Inter could be too good for Guidetti to turn down, but the terms of his loan state that he will remain with Celtic until the end of the season, meaning City will have to pay a fee to Celtic for the right to cancel the loan.
Facing the striker who has been so good for them would be a bitter pill to swallow for Celtic, but until City make a decision next month, Guidetti is a Celtic player - and will be relied upon to down Inter.
