At a time in this season too, Arsenal was not consistent and they were losing and winning but now they are trying to be consistent I was impressed with skills and pressures yesterday against PSV Eindhoven in the Champions League. But even at that I don't think Liverpool will give them chance to take over them in the Premier League. Liverpool has plan everything to take this season trophy so whoever that is coming they are ready to crush them. Arsenal might take the second position in the season and the first position is Liverpool (reserved). But the table might turn if a team plays exclusively as you said.
Quickly getting back to form such that it doesn't ge tto turn the season into a completely terrible one for them is what Arsenal was able to do that has helped them so far that they are now able to get some really good results, typically the game against PSV was an establishment of confidence and good form for Arsenal and now I believe they are going to strive even more to see if it were going to be possible they become a champions league top competitor because I know that for this season, the Premier league isn't one they may get at all.
