Celtic followed up their victory against Lazio at Parkhead a fortnight ago with another 2-1 win against the Italian side in Rome.
Olivier Ntcham scored the winner for Celtic with one of the last kicks of the game.
The goal came after a counter-attack in the 95th minute when Odsonne Edouard played in Ntcham. The Frenchman took a touch and then lifted the ball over the advancing Thomas Strakhosa.

Lazio had taken the lead after just seven minutes when Ciro Immobile's strike hit the back of Fraser Forster's net.
James Forrest then equalised for Celtic in the 38th minute. Mohamed Elyounoussi found him just inside the Lazio box and the winger rifled the ball past Strakhosa.
The win puts Celtic through to the last-32 of the Europa League with two games to spare.
Celtic's two remaining games in the group stages see them play at home to Rennes and away to CFR Cluj.
Celtic are level in Rome! 🍀
