Arteta's side crashed to a damaging 2-0 defeat against the Cherries in the Premier League last weekend.

That was Arsenal's first loss in all competitions since the Champions League quarter-final second leg at Bayern Munich in April.

Their response against Shakhtar was unconvincing, but they did enough to claim three points thanks to Riznyk's first half own goal from Gabriel Martinelli's strike.

Leandro Trossard missed a late Arsenal penalty that would have put a flattering gloss on the scoreline at the Emirates Stadium.
