What would be the reaction from fans if Arsenal finished 14th playing mostly younger players with a complete rebuild that got rid of veteran players like Aubamyeang, Lacazette, Ceballos, Pepe, Leno, Bellerin? And then maybe the season after that was 10th and after that could be 6th?
Would the fans be okay trying to build around Tierney, Gabriel, Guenduozi, Martinelli, Saka, Saliba, Willock, Nelson, Nketiah, Balogun, Azeez without any real immediate success for 2-3 seasons? Arsenal has a pretty good academy, and if they wanted to build around these players they could probably have a pretty good team with these young players leading the way, but if any measure of instant success is important, I don't know why any good coach would want the job.
As its currently constituted, you are forced to get some measure of immediate results with a team that has no identity. It's a mixture of a few good veterans, a few younger players who contribute, and a bunch of mediocrity and underachievers alongside them that clearly aren't the quality of player needed to be a good team. You also get considerably less transfer funds than the other teams expected to finish in the European spots. I don't see any real recipe to a top 4 place in the next few seasons with the current mix of players, and unless they start pumping in a lot of money to buy new players, it probably requires a full rebuild where they have a few really bad seasons.
