I believe they have whatever it takes to win the Premier League, I'm certain they're just ome striker away from winning a major trophy. They've shown they're capable of competing at the highest levels. Tale a good look at how they played against Real Madrid last season. I've always said trophies buy you time, but he's won nothing, the fans and management are just glad with how they've progressed. Next season, he needs to slap the gauge higher.
Arsenal and Arteta both needs to work on few things if they are looking for win Premier League it's all about mentality because without having strong mentality they could be not able to win anything in coming season as well.
Striker is their problem throughout last season, but their strategy is also problem for them Arteta fail to keep good strategy which keep his all players on good level for season they were facing problems which hurt them badly, and they lost their rhythm then have no chance of winning Premier League while Liverpool came from behind and clinch title. Coming season has never been easy because Liverpool doing good changes while Manchester City is also having some good changes which will keep them on good level, and they could be able to have better performance Newcastle United and Chelsea are also had good time to keep things on high, so Arsenal surely face challenging time.
