Slavia Prague
Slavia Prague arrive at the Arsenal match buoyed by a 5-0 victory away to Jablonec. Mubarak Suleiman scored twice, while Emmanuel Ayaosi also found the net. The hosts were again without Lukáš Provod, who missed two matches because of a fitness problem. Jindřich Trpišovský has left open the possibility of a return, but his captain's availability remains unresolved.
There is another question in defence. Ange N’Guessan scored at Jablonec before requiring treatment and being replaced. Štěpán Chaloupek, who came on for him, could join David Zima and Tomáš Holeš in the back three. Nazar Domchak is the likely goalkeeper after Jakub Markovič was absent for medical reasons on Saturday. Slavia may again rely on Wiktor Nowak through the middle, with Ayaosi and Suleiman offering pace around him. Their attacking improvement domestically will face a different test against a side unbeaten in this season's Champions League.
