even so Arsenal has shown progress in managing its squad and that is an achievement that continues to increase.
Wrong!
In fact, Arsenal never made any progress since 5 years ago. They never move forward. They get same result any season. They always finish 2nd, and being trophyless in the end.
They wasted hundreds million to rebuilt their team, and their result is not worthy with what they have spent.

I don't really see it as a waste. It is better to remain second every season than to get worse. Arsenal maintaining second position means they are close to getting the title of the Premier League. It is not easy to come out as second best every season; there are teams that are even struggling to be in the position of Arsenal, but they cannot. Having a second position every season in a league like the Premier League is not easy; it proves consistency. The reason why Arsenal is unable to win the league title is just a little problem they haven't been able to solve. Arsenal has a problem with a good striker, and they have always had problems with injuries to key players.
They are very close to getting a title, is that what you think? To me Arsenal is not a bad team and they are doing great we can not denied that fact, but Arsenal have been repeating the same mistakes for a long time now and you said been on the second spot if the league means they are close to getting title when they have been Finnish ton top 2 for a long now,
