We can't blame Arteta, he did very well but Liverpool also did the same thing so there must be a winner among the best teams well for this season it belongs to Liverpool. On the other hand we cannot ignore Arsenal's achievements in the Champions League even though they were kicked out but they were able to beat Real Madrid, yeah being in the semi-finals is a good record. Arsenal's weakness this season is that they have drawn more games, just imagine out of 36 matches 14 draw and only won 18 meaning they missed 28 points.
