Arsenal case this season is no longer the league title as that aspect of their campaign is looking beyond reach, I think their more focus will be the champions league as they have better chances their seeing that they are already in the semi finals and just wins away to become the champions of Europe that's if another team don't have anything to say.
The points difference between Arsenal and Liverpool is kind of much, and we have just few matches left to be played, so Arsenal have given up on the premier league title already, it’s impossible for them to win the premier league title this season, the only trophy which I know Arsenal can win this season is the champions league, that’s why their attention is currently in the champions league title.
Arsenal next champions league match will be against PSG, it’s going to be a interesting and tough match, the two teams are currently playing well, but it’s just going to be difficult to know who will be winning the match, because they both will want to qualify for the next round.
For their premier league campaign I think the struggle is for them to actually qualify for the champions league slot for next season.
Arsenal will be qualifying for the champions league next season, we have just 4 matches left to be played this season, and Arsenal which is currently in second position is ahead of Manchester which is in 3rd position with 6 points, from the way Arsenal are playing in the premier league, I know they won’t be losing the second position to any club, I know their performance is not really good in the premier league, but I know they will be maintaining their current position.
