Getty ImagesThe Premier League side saw several chances go begging as they edged out their Ukrainian opponents at the Emirates on Tuesday
Arsenal edged past Shakhtar Donetsk 1-0 in the Champions League, but needed an own goal from keeper Dmytro Riznyk to claim the win on a night when missed chances and injury concerns took centre stage in north London.
The hosts dominated the majority of the contest and looked set for a comfortable success when Gabriel Martinelli's shot came back off the post and deflected in off the unfortunate Riznyk just before the half hour mark.
But they wasted several chances to put the game to bed, with Riccardo Calafiori and Gabriel Jesus both guilty of poor misses before the break and Leandro Trossard seeing a weak penalty saved after the interval.
The hosts survived a nervy final few minutes to make it seven points from a possible nine so far in the Champions League, but Mikel Arteta's injury hit squad lost Calafiori to a worrying looking knee injury with Sunday's crucial meeting with Liverpool looming large.
