Factfile on Borussia Dortmund and Zenit St Petersburg ahead of the Champions League last 16, second leg tie between the clubs on Wednesday:

Form: Dortmund are enduring an inconsistent season in the Bundsliga and Saturday's 2-1 home loss to Borussia Moenchengladbach was their seventh defeat of the season. They are second in the table, but lie some 23 points behind leaders Bayern Munich. Jurgen Klopp's side are however into the semi-finals of the German Cup and are well-placed to progress to the last eight in the Champions League after a 4-2 win in the first leg in St Petersburg last month. Zenit responded to that and a 0-0 draw with Tom Tomsk in their first league game of 2014 by sacking Italian coach Luciano Spalletti. Former Russia captain Sergei Semak took charge for the 1-0 away defeat to CSKA Moscow at the weekend, which left Zenit three points behind Premier League leaders Lokomotiv Moscow.
