I doubt that Arsenal can win this round, indeed both teams still have the same chance, but in the next match Arsenal will face Munich away, of course this will make Arsenal feel pressured and I'm not sure that even if Arsenal uses all their strength, Munich will also do the same thing, let alone competing at home will make Munich more confident to win.
Looking down too much on this present Arsenal team is not something we should be discussing about. They’ve just proven to the whole world that they are also good and cannot be beaten like the did to the previous Arsenal team that had the last encounter with Bayern Munich. Just like they played and held Bayern Munich to a draw, so they will even play better in order to get a victory in the end. I am not certain which team will win in this match because of the quality of both teams but I believe they’ll all play great and try to win in which the better team will win.
Man City will play the day before Liverpool and Arsenal and it looks like they will be able to win that match easily, so Man City will be in first place in one day. Liverpool will also face easy opponents and most likely it will not be difficult for Liverpool to get 3 points. What's quite tough is Arsenal because they will play against Aston Villa, which has had quite a good performance this season. However, Arsenal still has a bigger chance than Aston Villa because Arsenal will play at home.
All three teams in the top three of the table would win their matches and still maintain their positions in the fight for the premier league trophy. Arsenal playing against Aston Villa is not even considerable to be a game to be loss by them. They are on the first position on the standings so I’m sure that they’ll do anything it takes to get three points in that match. Where I foresee a big change and a turn in this league fight is when any of the top three teams play against Tottenham who are also fighting to finish in the top four of the premier league table.
