If you spend 150 million in a transfer window, especially with no European football and finite resources, there should be a visible and indisputable difference in the quality of your first team.
Right now, at present, there is no certain quality in that list of names. No one who definitely, indisputably makes them a better team (although statistics suggest that Odegaard might)
In their position, playing catch up, they needed 3 quality players that would have instantly improved their first team.
They could have kept Odegaard as their main signing, kept Saliba and brought in Zouma, Neves and Abraham for the same money they paid on the other players.
It’s not a good window. They have overpaid for White, overpaid for a keeper with a ton of question marks over his quality, brought in a fullback who Portuguese posters claim could be laughably bad and signed a right back when they already had 3 at the club.
Absolutely nothing to suggest that Leno, Bellerin, Saliba, Guendouzi and Maitland Niles/Cedric (who can play RB or LB) wouldn’t have been just as useful as Ramsdale, White, Tomiyasu, Lokonga and Tavares.
They would have to be significantly better to justify a 150 million transfer spend. It’s a massive, massive gamble when more tried and tested options were readily available.
