The victory over Tottenham certainly means a lot for Arsenal and the three points achieved are very valuable because they were obtained at the headquarters of a team that is considered capable of stopping them. Arsenal have three more matches to complete all the matches played this season, two of which will be played at the Emirates stadium vs Bournemouth and vs Everton, one more match will be played at Manchester United headquarters. Nine points is of course Arsenal's target in these three matches. If they are able to maintain the performance they did when they beat Tottenham, perhaps Arsenal will get full points in every match.
If this scenario occurs, Manchester City will have to win all the remaining games this season to surpass Arsenal points tally. Tottenham is still Manchester City toughest challenge, winning is also their target so they can finish in a better ranking. It is still not certain who will win the Premier League title race this season because the two teams are only separated by one point.
3 matches remain for Arsenal this season, if they win all of them it will not be enough for them to become champions because they need to hope that their rivals defeat to help them become champions. Well, from what we see, of course Manchester City will not let Arsenal become champions because Manchester City always manages to play the end of season matches as well as possible. Yes, this season the clash between the two teams looks like last season because last season Arsenal also competed with Manchester City in the race for the title.
So, if you look at the 4 matches played by Manchester City, their opponents are not too difficult for them to beat. Maybe only Tottenham is said to be stronger compared to the other 3 opponents, but recently Tottenham have lost their best form so there is a big possibility that Manchester City will succeed in beating them.
