I am almost doubting Arsenal's resolve to end in the second place in the EPL standings this season. Liverpool may have won the league already but they wouldn't want to lose another game in a row after losing to Chelsea last weekend, so at least they will want to settle for a draw against Arsenal. And with Manchester city just 3 points behind Arsenal, if City wins Southampton in their match today they will be point parallel with Arsenal which gives them a high chance of taking over the second position on the table with Arsenal dropping to third place. All of these will be determined in their next game's after this very weekend all things being equal.
Arsenal and Man City will currently focus on maintaining their positions in the standings for a Champions League ticket next season. Arsenal facing Liverpool, will certainly have quite a hard time with the resistance from the Premier League champions this season. But Man City may be very favored to win in this week's match.
If Arsenal is unable to get a win, then what happens is that their position is shifted by Man City with a goal difference. We are approaching the end of the season, and the competition for a place in the Champions League is certainly getting more exciting, seeing the points difference, which is not too far between the teams.
