With last night's win Arsenal are one point ahead of Manchester City but City has one league remaining, this will be a serious title fight for Pep Guardiolla and his team, considering that Arteta also doesn't want to be said to be just a shadow of City this time or this year. Arsenal is ready to destroy City to win the Premier League title.
The situation remains the same as before and indeed it will continue to be the case likely until the end of the season. Arsenal are still trying to maintain their performance so that they continue to maintain their hopes of being able to stand as champions this season, it's just that with the conditions that occur now, especially the dominance carried out by Manchester City towards the end of this season and Arsenal's schedule which is still quite difficult because their opponents are not easy, this makes Arsenal inevitably have to remain consistent until the end of the season and hope Manchester City experience performance problems in easy matches because looking at the current schedule Manchester City has an easier schedule than Arsenal.
There are still 3 matches left for Arsenal and 4 matches for Manchester City so by looking at this, one defeat is already a sign of the club giving up at the end of the season.
Just like you rightly stated, the situation of the top two teams in the English Premier League is same as it were coming into the last the weekend as league leaders Arsenal were able to hold to secure a win against Tottenham Hotspur while Manchester City on the other side were also able to win against Nottingham Forest. Arsenal wants to break their 20-year jinx of not winning the English Premier League title while the reigning champions of England Manchester City wants to win the league title for the fourth consecutive time so I expect Mikel Arteta's men to be more determined to win the title ahead of others.
The interesting end to the English Premier League campaign would've been more dramatic and nervous if Liverpool were still very much in the race but even in their poor end to the season, English Premier League fans I think will still be thrilled with what Manchester City and Arsenal will give them
