It is too late for arsenal to fight t get the title of the league, even if they succeed in defeating Chelsea the point difference between Liverpool and arsenal it is impossible for arsenal to get to that point. It is possible for arsenal to beat Chelsea because they already have good performance this season than Chelsea but arsenal can be funny sometimes and Chelsea can be very tough in their games sometimes despite they are below in point. But for sure this game will be interesting and for me can't predict what will be the outcome of the game.
Arsenal never have time to fight for the title this season. They never ever very close to the Liverpool, which mean their hope to win the title already buried even since the start of season.
They have only target to secure UCL spot, but i consider them already save now. This is why i hope they lose in this game to ensure Chelsea can secure UCL spot for the next season too.
The only situation that is a burden for Arsenal at the moment is of course maintaining second place, because with a difference of 15 points from Liverpool, of course, it makes the opportunity to pursue the championship trophy very small and looks impossible, so it is better for Arsenal focus now is to secure their position in second place while remaining a specialist runner-up team

.
Victory over Chelsea will be very crucial to maintain their position, especially nottingham yesterday managed to win over Ipswich which makes arsenal pressure even heavier, against chelsea who started on fire, Arsenal really can't let their guard down and must get 3 points to delay Liverpool championship celebration faster apart from surviving the pursuit of nottingham in third place.
