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.
