Manchester City must rely on itself to win the EPL championship, the remaining four matches must be won if it wants to maintain its position as defending champion. The competition with Arsenal will continue until the end of the competition because the difference in points between the two is very thin. Arsenal will not just give up in the title race because they also really want to end the EPL title drought which has been very difficult to win so far. Manchester City and Arsenal must overcome every challenge in the next match, small mistakes will make their chances even smaller, Arteta and Guardiola will try to take advantage of the remaining matches to win the EPL title after failing in the Champions League.
If Man City wins, it looks like the first time a club has won the EPL 4 times in a row, the last time a club handled Man United 3 times in a row has been a long time ago. Arsenal and Man City have the same chance of winning the EPL title this season as long as both teams are able to sweep all remaining matches. It's just that Man City has a slight lead, if they manage to wipe out the remaining matches then they will win, but if Arsenal wipes out all the remaining matches they still hope that Man City will experience one defeat/draw and then Arsenal can win the EPL league. So in other words, Arsenal hopes that Man City will only draw once and Arsenal will sweep the rest of the match. The reason is that Arsenal excels in goal productivity.
On the other hand, Tottenham will have difficulty finishing in fourth place because Tottenham had 4 consecutive matches with tough opponents, against Arsenal (lost), then Chelsea, Liverpool and Manchester City. So it is certain that Aston Villa will finish in the top four until the end of the season.
