Scholes, Giggs, Butt, Nevilles, Beckham, Wes brown, Evans, Cleverely all stayed near majority near from the start right to the end retirement days of SAF.
Then he also bought Carrick, Rio Ferdinand, Rooney, Hargreaves, Young, Zaha, Keane, Sheringham, Andy Cole, Alan Smith, Smalling, Jones, pallister, Hughes, Ince, Dublin, Bruce, Irwin and so many more that I can't be bothered.
I'm not sure why you think SAF succeeded more from buying players like Haidara and Kamara when that reminds me of the djemba djemba and Kleberson transfers.
I'm not saying we should have a full 11 players of English players at an English club - but I do think it's an underrated aspect of some clubs to have some homegrown players.
Even when people are talking about the slight improvement of Arsenal this year - whilst I don't rate Arteta, I don't think it's a coincidence that Arsenal bought Ramsdale, White, Using players like Tierney, Saka, Smith Rowe all in the first team squad regularly and they have improved a bit compared to the last couple of years.
