The emphasis was on spending 90 - 100m player when you've got someone who 2 years younger and is able to reach the heights that Sancho has. I don't doubt the fact that Sancho could work wonders for us and we probably do need firepower to ensure that we deliver a PL title soon. However, there are other areas that would need upgrading as well aka CM (if Pogba or Bruno are injured), DM (Is the Matic resurgence temporary? will age catch up next season? can he be consistent? will he be found out by the bigger teams? can we depend on McT & Fred to deputize when required?, CB (We need a CB that can be relied on. Maguire has been shaky at times and is slow and Lindelof albeit he's proven to be a good partner for Maguire, is he a long term option when it comes to winning the PL?
Do we need a 90 - 100m player or can we do with a 40 - 60m instead? I've already heard the shirt sales and marketability options... We've already got Pogba, Bruno, Rashford, Martial, and with Greenwood's rapid growth, not long before he becomes a hot marketing commodity as well.
Let me reiterate as a fan, I would be more than happy to get Sancho but we do not have an infinite transfer budget, should we be looking at the bigger picture?
