The summer transfer season is still going and there are perhaps more negotiations and transfers completed by Arsenal in coming weeks. They are heading towards a season with a big task of beating many competitors and lifting Premier League trophy after many years. Arteta has done his management well so far, changed Arsenal from a weak team to a very competitive one, but he and Arsenal need a title to mark his management in Arsenal as a successful era for the club and his coach career.
Arsenal got some really big transfers in this window and i think they picked the right ones this time. The only question is if they are all able to play good with each other if they start well they can try and attack the title. But in the premier league there are so many good teams that honestly you cannot know if they will win the title. But i think they are on a good road this season to try and surprise everyone
It's true that the summer transfer window is still on and will still be open to EPL teams until the first week of September I think but the thing is, we have all witnessed several transfer windows in the past and how other top teams in the league makes judicious use of transfer window to strengthen their squad except Arsenal who plays with the widow. Several times they have chased a player only for the deal not to materialize. I'm only commenting on what I have seen the team do, I really want Arsenal to buy players so they can compete properly like the other top teams.
