We can't say that Arteta has given up on the title race because Liverpool has played 28 games and Arsenal has only played 27 which means they still have an outstanding match to play which if they win, the gap will drop from 13 to 10 points and who knows if anything can happen to Liverpool towards the ending periods of the season such that Arsenal may become resilient and surprise majority of people by overthrowing Liverpool at the top of the table. Due to how Arsenal have been jeopardizing their chances of getting closer to Liverpool has made people not to put their trust on Arsenal again but we should not forget that this England Premier League is always full of shocking moments especially when the season is getting near to end. Arsenal should not keep settling for the second position, Arteta and his boys should try and use new formats that will work for the team and lead them to winning trophies instead of always ending as a runner up to the champions.
Just one game in hand with 13 points lead, and their attack is totally crap mean things are already gone out of way for title they need to work on for consistency and also have some good depth into their performance with this mentality Arteta can't win title here in Premier League.
Liverpool done enough job for win which giving them good advantage while now Manchester City is also ready for taking second spot which is challenging for Arsenal because they needed to stay good if they want to have any chance 11 matches are remaining surprises are always part of Premier League but still title race is ended. Three spots are wide open for few teams which are looking for European chances competitiveness is always important while quality is on same level, but few clubs needed consistency which will make things interesting in coming rounds.
Arsenal still have a chance, but it's obviously very tough because they are not only required to play well consistently, but they also have to hope that Liverpool will struggle in the following games. But if Arteta can be realistic, then it would be better if they quickly waved the white flag in the EPL race, so they can focus on other competitions (eg, the Champions League), and that might increase their chances there.
