The rebuilt is going to take longer than the fans think. If you watch this recent interview with the owner's son, you more or less can reason the rebuilding strategy is basically an injection of funds early on for young players and let them develop over years. You can see the owners would mirror Arsenal's rebuilding based on Kroenke's NBA basketball team Denver Nuggets.

I don't expect to see another round of player buying to straight up boost squad quality. In NBA, the general equivalent of this is called the 'luxury tax', where when a team signs multiple superstars on high wages, that team have to pay NBA a tax after going over a threshold. Denver Nuggets (Kroenke's basketball team) historically do not pay the 'luxury tax'. In other words, even if Denver Nuggets have the opportunity to acquire quality to better their chances, they do not want to pay.

Denver Nuggets is currently banking on their talent called Nikola Jokić they drafted (signed for free) in 2014 and added pieces around him over time. 6 years later, Nikola Jokić became MVP but the team hasn't won anything. The Kroenke will say they have ambition to win everything in sight, big club mentality, etc; but time and time again, they rather use the passing of time and call it a project instead of spend, spend and spend.

'Draft/buy bunch of young talents, don't sell them, let them grow organically over the years and profit from top4 (soccer) or playoffs (basketball).' That is going to take a lot of time and Arteta will get time from the owners. The Denver Nugget coach is still on his job since 2015. You get time, but not a whole lot of money.

The interview with the son.
