I'm surprised you are saying this, was there anytime they have not mention Arsenal as a club at the heart of premier League, when trophies are called Arsenal will always be taking serious even if they have failed numerous time because changes could occur and when it does it will be the time we would be thinking they will not even reach the fourth position on the table, Arsenal victory will come as the way Chelsea trophy came, at the least expect of everyone, it might not be this season or even the next but one day we would see them there so let's not think about them as people who are coming from relegation.
I am sure that Arsenal will be very good this season in the PL, I think they have integrated some excellent players and this will change their style a lot and I consider that now they can be more consistent, they are good, they proved it by beating Madrid in the UCL, but they have to win more often, Arsenal's mistake is that they always get confident and give the best game of their lives and then lower their level, these things are disconcerting, and that has caused them to lose the opportunity to win in the PL many times.
Arteta Leaves Door Open for More Arsenal Signings After Gyokeres ArrivalAmong the names strongly linked with Arsenal is Eberechi Eze, the Crystal Palace playmaker who brings dribbling ability, creativity and an eye for goal. He would provide added spark in attacking midfield, potentially rotating with or complementing Martin Ødegaard.
While there has been no official comment on Eze from Arsenal, speculation continues to grow, particularly after Arteta’s refusal to rule out further business. His tactical flexibility means a player of Eze’s profile could fit naturally into multiple roles.
Arsenal’s recent pattern under Arteta has been to wait for the right moment and the right price. If an opportunity emerges before the window closes, the club is now in a position to act decisively.
