The performance of Arsenal every week keeps improving in all round because this season the team looks so much better this season and their team work this can't be compared to that of other teams in the same fight foe the league which is the major reason why I think they more focused and more ready to beat any team they come across right now in the league because even when they are yet to score goals in any match they are never given up as they have the believe that they will be victorious in the game with their level of performance.
Arsenal's remaining fixtures may look a bit difficult compared to that of Liverpool and Manchester city but their performance and form is second to none as the teams they will face is not in a better position nor form than them and the way they have so much confidence in all their games they can beat anyone regardless of where the mat h is taking place, the other teams may have matches against other smaller clubs but the outcome may not be as expected because right now the smaller teams are looking forward to ending the league in a safer position so every team is as dangerous and well prepared as the big teams they may even be in better preparation since they will take any advantage to get 3 points from any big team.
No as far as I can see the remaining fixtures are about the same for everyone who is playing for the top. There are little differences in terms of the number of home games, but it probably won't really make a difference.
Arsenal does at least show a level of consistency that seems to be better than what they have shown last season when they started making irritating mistakes in the last two months of the season. Now this should not be the case and the whole Arsenal team along with their coach probably have learned their lesson.
But it will be a tough fight as everyone of those three teams is practically able to win all of their remaining games. I guess that none of them can afford a loss without suffering from hefty consequences.
