Their strong league start has been built on a solid, mean defence, with just five conceded after that loss in Dortmund.

Key to that has been the form of the Hungarian international keeper Peter Gulacsi, who kept the score down on Saturday.

He suffered an horrific knee injury when the sides met in Leipzig in 2022, which kept him out for 16 months. But he has battled back to reclaim his number one status and will be aiming to carve out a better memory from this meeting with Celtic.

At the other end of the pitch, there is a dual threat provided by the pairing of Belgium’s Lois Openda and the young Slovenian Benjamin Sesko.

The duo combined to give RB Leipzig the lead in the Westfalenstadion at the weekend and will likely provide Cameron Carter-Vickers and company with a few headaches on Tuesday.

Both came to the club in the summer of 2023 and contributed greatly, Openda ending the season with 28 goals.

It is Sesko who is slightly ahead on seven at the moment, scoring all three of his team’s Champions League goals. Celtic will do well to prevent him adding to those.
