The Champions League returns for matchday two on Tuesday, with a huge clash between Borussia Dortmund and Real Madrid the standout fixture.
Dortmund twice scored late equalisers against Madrid last season to top their group, before Zinedine Zidane's men went on to retain their European title.
Elsewhere, the top two in Group F - Manchester City and Shakhtar Donetsk - meet at the Etihad Stadium, while both Tottenham and Besiktas look to continue their winning starts.
Here, we look at the Opta numbers from Tuesday's fixtures.
Sevilla v Maribor
11 - Sevilla have won 11 of their 15 Champions League home games (D1 L3) and have never failed to score in any of those 15 matches.

Spartak Moscow v Liverpool
