They have big reason to at least avoid a defeat in this match but if possible, they will try to get three points that are helpful for them to refresh themselves after disappointed defeat in Champions League semi final. Three points will help them reducing a lot of pressure in two last matches after a big clash with Liverpool.
I believe Arsenal won't want to lose this match but they perhaps are not strong enough to beat Liverpool so it's likely that they will share 1 point after this super sunday match.
Two of the last three games were very tough for Arsenal (vs Liverpool and Newcastle). But this match is just a formality for Liverpool who have secured the EPL Trophy, perhaps the same thing happened when they lost to Chelsea last week.
The game against Newcastle is a bit tough, but the result of this game will not affect them anymore if they manage to beat Liverpool because Arsenal only need +3 more points to secure a ticket to the UCL next season.

Truly, this match means nothing to Liverpool's win anymore, but I tell you, Liverpool will still deliver in it. I don't even know who sets such a crucial match between the two big clubs at this time of the season, it's pointless to me. Well, I still believe that Liverpool's team would want to impress their fans more with this match and continue to show their supremacy in the EPL this season. For this, Liverpool would play less for glory, but for training and fun. So watch out! And I see Liverpool easily winning this match judging by what Arsenal has been playing lately.
