What's interesting is that in 21/22 and before Arsenal were only buying U25s to replace all those senior, overpaid, underperforming players.
Then in 22/23, they bought Marquinos 28, Trossard 27, Jorginho 30, Zinchencko 25, Jesus 25. They switched to 25-30 year olds (plus Kiwior and Vieira) and went for quantity over quality. They stretched their budget very thin, buying 7 players. Some would argue it nearly worked as well, having the depth to finish within 2 point of winning the league. Problem is, they stretched their budget too far and now have some average deadwood that needs shifting. Out of those 7 players, I'd only retain Trossard and Jesus as squad players. In my opinion, they mostly bought badly.
As they moved to 23/24, they spent big on Rice, Havertz and Timber and got Raya in on loan. They changed strategy again and went for quality over quantity. Ditto 24/25 with Calafiori, Merino, Timber plus converting Raya's loan.
My conclusion is that I think Spurs should skip that second stage of buying a large number of 25-30 year olds. We should stick to signings like Dorgu who is 19/20. Let's plug the squad gaps with these types of signings. Ederson is 25, Delap is 21, Joao Gomes is 23, Cirkin is 22, Wharton is 20. All these examples of links feel really good to me. I'd stick with this transfer strategy and let Ange do the rest.
