The only way your point adds up is if the expectation for EtH joining us is that we wouldn’t make any signings the summer he joined. How can I judge EtH off a squad he never coached or played with.
Arteta and Klopp had to use what they had for their 6 and 9 months respectively. EtH was never in this position as he started by making big signings.
I will continue to laugh because Saka and Martinelli were 18 and 19 and were not in Arsenal’s strongest lineup then, Saka was actually playing LWB then. Saliba was on loan at Saint Etienne and Ozil was banished from the squad or injured after a handful of early games under Arteta.
Your Bruno and Rashford point point makes no sense, much like the rest of your post. My criticism of them is in terms of us winning the league or CL with them, I’ve not said they aren’t good players. They easily get into the Arsenal and Liverpool starting lineups I highlighted above which is what is relevant to the conversation rather than your strawman argument.
Again I provided you with trends which you seem to ignore. A team that finishes 5th 6th 5th (Arsenal prior to Arteta joining) in three seasons clearly has worse prospects than one that finished 3rd 2nd 6th (United before EtH). We had a shitshow of a year under Ole/Ralf but it was not representative of our true level.
