Sporting could be missing Jovane Cabral, Tiago Tomas, Sebastian Coates and Ruben Vinagre in midweek. Defender Pedro Porro returned from injury in the cup at the weekend. Luis Neto is on standby to replace Coates at centre-back against Borussia Dortmund on Wednesday. Mats Hummels is suspended after his controversial sending off against Sporting CP was upheld. Thorgan Hazard tested positive for COVID-19 after playing for Belgium during the international break and misses out here. Marius Wolf, Dan-Axel Zagadou, Gio Reyna and Youssoufa Moukoko remain doubts and Dortmund could be without 10 players in total on Wednesday night. Gregor Kobel and Mahmoud Dahoud were at least back from injury at the weekend and Raphael Guerreiro's recent return is a further boost for Borussia Dortmund. Dahoud hasn't played since September but may be required from the start here as Dortmund find themselves down to the bare bones. Summer signing Donyell Malen will be relieved after scoring his first Bundesliga goal of the season at the weekend.
