this match is likely going to be won by Newcastle because they are the once that needs results badly and not arsenal because arsenal has nothing in to lose if they lose this game because they are already second in this game so I will want Newcastle to win so that they can make it to champions League come next season
Newcastle does need full points when playing at Arsenal's home ground, but if Newcastle does not get full points in the away match or even the result is a draw, it will not be so threatening for Newcastle to be eliminated from the Champions League zone this season. Because Newcastle has one more match to keep themselves in the zone so Newcastle does not have to worry if in the match against Arsenal they do not get full points. Because the last match for Newcastle this season is against Everton who are not much better than Newcastle in terms of strength.
Secure three points when facing Arsenal upcoming match not only get UEFA Champion League spot for next season but also Newcastle United have bigger chance for finish at 2nd standings position. Recently, Newcastle United has two points remaining with Arsenal if win upcoming match automatically will rise to second standings and have to win at last match against Everton.
For upcoming match against Arsenal, I think Newcastle United won't losses three points and secure the UEFA Champion League spot standings early behind have one match left against Everton, however bigger opportunity get 2nd standings place if can win in last two matches left.
Premier League show most interested league to be top fourth standings team, until two matches left only Liverpool have secure their position for qualifying to Champion League next season. Have six teams left fighting for five Champion League ticket and likely upcoming match will know which one team will qualify or drop outside Champion League spot standings.
