After last two matches, Arsenal dropped points. I think this match will be a prove to the general public and their fans that they are back strongly to keep competing for the Premier League title because they need such a comeback in their performance in order to maintain their chance of being title contenders this season because they actually missed their chance, which will make them go above Liverpool in their last two matches.
Winning the first game of the year after dropping from first to third place with more games played isn't something to brag about just yet, especially against a poor Crystal Palace side that hasn't won Arsenal since Patrick Vieira first season in charge, and since he left, it's been a playing ground for Arsenal.
Nevertheless, Arsenal had a great performance today; they played well with the intention of winning the match because they really needed these three points. Arsenal has now moved to the third position with the same points as Manchester City and Aston Villa. This is a tough time in the Premier League. All the top teams with the hope of winning the league will be very focused on all their matches; they will not want to lose any match, and the match between them will be the determinant of their respective positions.
The league is currently too open to discussing title challenges, and we are approaching the point where losing a point could mean a lot, but we are not there yet. A lot might change for a few clubs that have some of their best players at the AFCON and Asian Cup if they stay longer than expected.
