Christoph Kramer's Celtic Park experience has never left him.
The Borussia Monchengladbach star featured in the German side's Champions League group stage victory over Celtic in October 2016.
And it's not just the victory that the 31-year old German international looks back fondly on.
Speaking to DAZN, Kramer was asked what his favourite game has been at club level and despite playing at the likes of the Nou Camp, Stadio Olimpico and Allianz Arena, the defensive midfielder holds his Glasgow experience in the highest regard.
"My best game at club level was with Gladbach in Glasgow against Celtic", Kramer confessed.
"I've never experienced such an atmosphere.
"We won 2-0 and it wasn't a footballing treat - but the atmosphere was amazing.
"We went to a pub with some of the team afterwards and it was a day I will always remember."
Kramer is just the latest of illustrious names to praise the Celtic support. Even though on this occasion, the result wasn't the most memorable for the Hoops.
