I don't know how legit the statement in that image looks but if he really said that, then it's not encouraging to his players cause it sounds like a coach that's already given up, all hope is not lost and it's still possible for Arsenal to fight to the end and try to win this season's tournament, we've seen Manchester City do it in the past so Arsenal should try to do it also, I know it's not easy cause Liverpool's form is very outstanding but there's still lots of games to be played before May.
Injuries have really ruined Arsenal's chances this season, it started with their key player Saka, then other key players join the list of injured players but it's not over until it's over, the lose against Westham shouldn't make them lose hope already, there's a possibility of Liverpool loosing in matches ahead and they could capitalise om that, therefore giving up at this point is not very encouraging.
This season all what Arsenal needed to go hard on and be competitive with Liverpool was just Arteta to sign a central forward that is good and known to have goal scoring qualities and perhaps with addition to a rotation for Martin Odegaard, and not this flimsy excuses he's bringing up to the media. I think if Arsenal management wants to really win a major trophy then Arteta should be replaced else we'll still get to listen to this similar excuses which has turned to a series for Arteta every season. I don't see anything extraordinary Liverpool are doing this season with points that Arsenal are already giving them the trophy on a platter.
