Arsenal is playing well now but I also do not think they can catch up to Liverpool who is 12 points ahead. To catch up Arsenal would need to win every game left which is little impossible. They still have to play tough teams like Liverpool and Newcastle and they are also playing in Champions League which will make players tired. With all these games it is hard for Arsenal to play their best. So it looks like Liverpool will probably win league this season. They have big lead and do not have as many games to play since they are out of Champions League. Maybe Arsenal will come in second which would still be good finish.
The UEFA Champions League is only meant for the main title contenders and not some random team that doesn't even beat the odds to level scores with competitive teams. Arsenal have been one of the very dashing club this season, despite their amazing performance, they're knocked out in almost all competitions remaining the UEFA Champions League and their hunger for the EPL title, don't you think it's time for the club to win after such a longterm.
Arsenal should simply forget about the EPL title this season because they're only known for one thing, been the bottlers team for the EPL title every season. It's been selectively consecutive and this is not good for an elite side like Arsenal. By the way, what's the main role carried out by Mikel Arteta who everyone thinks his time is get seized up by the team's management, he kept making promises that he's unable to keep to.
