Mate, you really need to work on your tone, you come off as a petulant child. Let me ignore that and try to answer you
- In summer Poch didn't want a striker, he wanted Sessegnon, Lo Celso, N'dombele and Fernandes (Dybala was purely opportunistic), he got all except Fernandes.
- Poch compounded that by not keeping Llorente
- Any backup striker will always be sub par as everyone knows Kane is and will be #1 until he leaves Spurs, so no striker anywhere near their prime is interested
- Chelsea, United and Barca are struggling to get a decent striker who they can offer stupid wages to and almost guaranteed starting spot, but you think it's easy?
I'd argue the striker would have gone a long way, but a clear backup plan is putting Son center and SB in Son's role ..
