The time to buy Sanchez was when barca bought him or when Arsenal bought him. We have just bought Sane and Jesus on top of Sterling the season before. Timing is wrongIf we play with a front 3 then 6 players in the squad is a reasonable number:
Aguero, Sanches, Jesus, Sane, Sterling, Roberts.
That line up assumes Navas and Nacho go, but that looks likely. I remember Keegan saying once that 6 strikers was a good number - that was rubbish but 6 players covering 3 positions and when many of those players can interchange is fine for me. You could easily start 3 and sub on 2 most weeks.
I also suspect Sanches could do a job in the midfield 3 behind as well in the Silva or KDB role.
I can understand why we'd be linked with him. You look at Arsenal, and the one player who gave them something in the big games, indeed all the games was Sanchez. he is a fantastic player, but I do think he maybe at his best now, or just past it, and it's the one place in our squad where we are strongest.
An argument for signing him would be instant competiveness. It would be Guardiola's 2nd season. We need to be competitive and transfer mkt is going to be insane. Liverpool, Utd, Chelsea plus foreign clubs going to be chasing a limited group of players. Arsenal might throw everything at it trying to get back in.
