- The two sides have met four times at the Camp Nou, with two Barça wins (1964/65 and 2007/08 season) and two draws (2003/04 and 2004/05 seasons).

- FC Barcelona has entertained Scottish teams five times, and the only time they lost was 2-1 to Dundee United in the 1986/87 season.

- Barça have not lost a home Champions League match for three years, the last defeat being 2-1 to Rubin Kazan. Since then they have won 14 and drawn three.

- Celtic have never won away to a Spanish league club. So far, they have lost nine and drawn three.

- Xavi Hernández has completed 236 of his 266 passes this season and is top in that category. Busquets and Mascherano are second and third in the same ranking.

- But Busquets will be missing from tonight’s game after getting sent off in the last match at Benfica.

- Celtic’s Wanyama is one yellow card short of a suspension.

- Celtic’s win at Spartak was their first in 21 Champions League away matches.
