Right now, they are having only one challenging game against Manchester United which is surely not easy but this all depends on Manchester United as well which is one of the worst sides with their unpredictable nature and inconsistency which bring them down, and now they are having no chance for the top five spots.
Manchester United are one of the most inconsistent team in the league this season but when playing against them you can hardly predict the outcome of the matches even though they end up losing most of the matches. Arsenal probability of winning is higher than that of Manchester United but nothing is certain yet. Manchester United can actually put up a good fight against Arsenal so Arsenal need to be at their best against them if they want to keep their title hopes alive.
As Arsenal has one challenging match, also Manchester City has on challenging match which I think is the last match to be played and that is when they will play Tottenham. Manchester City is hot but I can not predict such a match.
Manchester City against Tottenham will definitely be a tough one too, Tottenham already lost to Arsenal and they won’t want the same to happen against Manchester City but if City are strong and determined Tottenham shouldn’t be a problem. It will be an interesting game surely but won’t be easy to predict.
