Alexandre Lacazette came off the bench to score the only game of Saturday's win over West Ham before declaring he is pleased to have given head coach Mikel Arteta a headache.
The France international striker has been playing second fiddle to Eddie Nketiah of late following an indifferent run of form in front of goal.
But he came to the rescue as his 78th-minute strike, awarded by VAR after originally being ruled out for offside, secured a 1-0 win over the Hammers.
Arteta admitted after the game that having to choose one of either Lacazette or Nketiah was making his life difficult - but Saturday's match-winner would have it no other way.
