Arsenal do lack consistency,  that’s the main problem they are having every season. Arsenal were supposed to win the last Premier League title, but the only mistake they made was losing to Aston Villa towards the ending of the season. Their performance last season was just better than other seasons, they fought for the league tittle till the last match was played. Let's expect improvement in their performance in the coming season. Let's see if Arteta will be able to win the trophy for Arsenal, or they are still going to end the season in the second position, which they are used to.
