Adrien Rabiot has described Celtic Park's European atmosphere as 'incredible'.
The Frenchman currently plies his trade for Marseille, but turned out at Parkhead for Paris Saint-Germain in the Champions League in 2017.
A star-studded PSG team, including the likes of Neymar Jr, Kylian Mbappe and Edinson Cavani, ran out emphatic 5-0 winners that evening.
Rabiot was recently asked about the best footballing atmospheres outside of Marseille's infamous Stade Velodrome: "With PSG, we played against Celtic Glasgow," he told CARRE.

"We were winning 5-0, but the guys kept singing, it was incredible, I'd never seen that before.
"You know, it's the emotions you experience, even though you're the opposing team.
"Even my family was in the stadium, they still remember it, because it's the things you experience. You say, the guys took 5-0, but they're singing all over the stadium.
"So it's things like that that mark me, but Marseille, I place it at the top."
Rabiot departed PSG for Juventus in 2019.
He then spent five years in Turin before returning to his homeland with Marseille last summer.
The 30-year-old has enjoyed a fine campaign with the club, scoring nine goals in 29 Ligue 1 appearances, helping them to a second-place finish.
Marseille will resultantly play Champions League football next season, where they could come up against Celtic.
Rabiot would undoubtedly relish another trip to Glasgow's east end after giving his 2017 visit a glowing reference.
