Arsenal can get the EPL title when Arteta is really ready to give up the UCL and focus more on winning the premier league title. But that is very unlikely and it will not be possible for Arteta to easily ignore the UCL title. Because in my opinion Arsenal do not have strong experience to win titles in the UCL or in the EPL. If Arsenal focus more on one of these competitions, I am sure they can win the title they want. And for me if Arsenal fail in the Champion League but successfully win the EPL title, it can build the mentality of Arsenal players to fight for titles in more prestigious competitions in the next season.
