bundesliga.com rounds up everything you need to know ahead of the Matchday 6 clash at the Borussia-Park.
Thorgan Hazard's (r.) Gladbach just need a point to reach the last 32 after earning a 2-2 draw on the road against Villarreal CF a fortnight ago, while victory would seal the Rhineland club's place at the top of the group. Their Swiss opponents, meanwhile, must win if they are to stand any chance of progression.
Former FC Schalke 04 forward Mario Gavranovic remains sidelined with a knee injury, with Gilles Yapi (knee, pictured), Berat Djimsiti (foot) and Mario Gavranovic, who have all scored in Zürich's Europa League campaign this season, also ruled out. Defender Raphael Koch is rated as doubtful.
Havard Nordtveit (pictured), on target in the sides' 1-1 draw in October, is expected to make the Borussia squad despite sitting out training on Wednesday, while Martin Stranzl and Max Kruse are both battling to be fit. Branimir Hrgota is ready to step in should Kruse fail to prove his fitness.
Tunisian international Yassine Chikhaoui missed the teams' previous meeting through suspension but Zürich’s top scorer in the domestic league (seven goals) has been singled out as the Zürich’s dangerman by Gladbach boss Favre. “He is a quality player,” said the 57-year-old at his pre-match press conference.
Having scored crucial goals in Gladbach’s most recent Bundesliga and Europa League games, Raffael will be looking to continue his fine scoring form on Thursday. The Brazilian forward, who won two league titles during a two-year spell with Zürich, ended his seven-game Bundesliga goal drought against Hertha Berlin on Saturday.
Lucien Favre (pictured), Gladbach head coach: "We desperately want to win the game and make sure we stay in first place."
Raffael, Gladbach forward: "We have a great chance to reach the second round and need to make use of our home advantage."
The Zürich game comes at a good time for Gladbach, who returned to winning ways against Hertha on Matchday 14 following three consecutive Bundesliga defeats, and are unbeaten in six European home games. The visitors, meanwhile, are second in the Swiss Super League despite a 2-1 defeat at FC Thun last weekend.
Nordtveit's brilliant long-range strike earned Gladbach a hard-fought 1-1 draw when the sides played each other in Switzerland on Matchday 2 - the only previous meeting between the two teams. The Norwegian midfielder levelled matters after Franck Etoundi had given Zürich the lead.
Gladbach: Sommer - Korb, Stranzl, Jantschke, Dominguez - Kramer, Xhaka - Herrmann, Hazard - Raffael, Hrgota
Zürich: da Costa - Nef, Kecojevic, Alesevic - P. Koch, Elvedi, Kajevic, Buff - Chiumiento - Etoundi, Chikhaoui
