Arsenal made it back-to-back home wins in the Champions League with an unconvincing 1-0 victory over Shakhtar Donetsk, settled by an own goal from goalkeeper Dmytro Riznyk after 29 minutes. In an open contest, Leandro Trossard missed a second-half penalty, saved by Rizny's legs, before David Raya was forced into a smart late save.
