I doubt if Arsenal can win the trophy no matter how hard they try because the point difference is too much assuming the point difference is like that of Barcelona and Real Madrid I would said it is somehow but 12 points difference and there is 9 more match to go..., it is not possible because Liverpool on the other hand can not even allow that to happen after losing the champions league and EFL cup ah, it can not be possible so Arsenal should just play and focus more on the champions league because that's the only place they have hope now.
Arsenal have no chance of winning the title. Each team will play only 9 matches. The difference between Arsenal and Liverpool is 12 points. Liverpool is unlikely to lose more than 4 of the next 9 matches. Liverpool's performance is still strong enough.
Also, even if Liverpool loses points, it is not guaranteed that Arsenal will win their next 9 matches. Arsenal has lost points in three of the last 4 matches. Arsenal will not be able to win any of the upcoming 9 matches. So the Arsenal coach should now focus on the match against Madrid in the Champions League. If they can win against Madrid, Arsenal has a chance of winning the Champions League title.
