That won't last long, because in 3 days Man City will face a team that has not won in the last five league matches. Even though Bournemouth are playing at home, their performance cannot be superior when they have guests as big as Man City.
A difference of 4 points will become a difference of 1 point in the next few days, because I am very confident in Man City's victory in the next match.
I know, Bournemouth once beat MU by 3 goals without reply at Old Trafford, but MU and Man City are different this season. I see Man City as more solid so they deserve to be at the top of the EPL standings.
And as for Arsenal, I'm sure they will continue the winstreak they have been on. Newcastle are a little stronger, but I still see the discipline of Arteta's men being very good lately.
And what do you think would happen if the standing continues like this until the end of the season? Liverpool will be definitely crown the EPL champions. No point is too small in this league and that 1 point will make a big impact. With the current happenings, Manchester city is still the favorite team to win the EPL because Liverpool who are the major contender is now faced with injuries crisis while City major players are just recovering from injury. This situation has reduced their chances for now.
To me, if there's any team that is more deserving to be at the top of the EPL table right now, that team should be Arsenal. For the past three seasons now, Arsenal is proving themselves to be once again a team ready for tittle but always fail along the way. Unfortunately, the top spot is not occupy by a mere deserve but by team performance.
