I don’t see a chance of Arsenal coming back into the title race this season. I think this post is just his way of consoling Arsenal supporters and encourage them not to give up and continue watching and streaming their club games. It is over for Arteta and Arsenal this season, Liverpool should be given the title already.
Although I'm sure Liverpool won't play badly in the rest of the season, however, the league still has 10 matches left, which means there is still a chance for Arsenal to catch up with Liverpool's points. If Liverpool plays badly in the rest of the season and on the other hand Arsenal wins all the remaining matches.
We who follow the matches in the Premier League must know how much the difference in points between Arsenal and Liverpool means. It will not be easy to catch up. Especially since Liverpool has hopes for several trophies this season.
