The two elephants will be meeting and is actually going to be the most interesting match on that weekend because the match will determine the club that would become the second or the first position of the premier League because if Arsenal eventually wins Manchester City then we can say that they have the upper chance of wining the premier league because they will beat Liverpool in terms of there points while Manchester City will remain on the third position, although I'm only assuming because nothing is certain yet but with the look of things this match will be nothing like Manchester City and Liverpool because I believe there would be wining on this match.
Arsenal are not bad but I'm not sure of what these outcome is going to be like. But what if Arsenal win Chelsea and then draw Manchester City, that will start to look like beginning of success to Arsenal because not winning the Premier League is my biggest fear right now as I'm already having some doubts about there success in the Champions League. I think it's easy for Arsenal to play just a match here in the Premier League and draw than for them to do that in the Champions League, no way Real Madrid or Manchester will show them mercy.
It seems like Luton town might not be relegated, they are now ahead of Nottingham Forest that was trying to leave the danger zone but I'm impressed with the Work Luton has put into their games recently even though they have lost a lot of matches but it's better than leaving the Championship after a season and the return back there without any valuable contributions to the club.
Yeah if Arsenal draw the match against Manchester City then they will be at an advantage because they will have more points over Manchester City but just like you mention in as much as Arsenal is also very good in performance but I doubt if they can be able to lift the premier League trophy this season because the clubs that are competing on this premier League is too strong but if they can able to hold Manchester City draw and win there remaining Matches then we can say that the premier League belongs to them but the problem they will have on this match is that Pep Guardiola will use all he has against Arsenal in other for them to win the match, however from records of Manchester City matches against Arsenal it has it that Manchester City has the highest wining, so perhaps that's why Arsenal wining Manchester City will somehow seem impossible.
Also in terms of Luton they have manage to improve more on there performance that's why they have move alway from the relegation but although they are not yet completely safe because if they are not able to win more of there matches they will likely return back to the relegation zone.
