Since Manchester and Arsenal are eliminated in the Champions league, this make the premier league more tough because before the elimination of Arsenal they drop point and leave their position to Manchester City the same thing with Liverpool. So with this reason, I’m very sure Manchester City will be a threat to Arsenal and also Liverpool. I think Manchester city will use the first position as an opportunity and motivation to put in more effort in the premier and fight for the title this season.
Furthermore, I can give Manchester City another hope for winning the title this season. Because they at the top of the table, and they have got eliminated in Champions league which means they are full concentration will be in the premier league, because this is the only league they have hope to get this season. And they have already at the top of the table, so the only thing they need now is to continue winning their matches, so let see if Arsenal are going to do something positive.
For me, there is nothing positive arsenal can do, I rather stick my guns with Liverpool as contenders rather than go with arsenal inconsistency.
