While I agree with what you're saying, I have issue with the term "non-starting 11". At the level we're now at, at the level we aspire to, the concept of a starting XI is outdated and just wrong. We need to talk about a starting 15 or thereabouts -- the subset of the first team squad who get regular game time. Sure, there'll be a core group who start every big match when fit, but there needs to be rotation.
To the people saying £60M is a lot of money for a squad player, I'll say that he's not a squad player. We expect him to go straight into a front 4 rotation with Son, Kane and Kulu. For a low-risk player who has good Premier League experience, that's absolutely fine by me. Far better than getting two Carlos Kickabouts for £30M each and hoping they come good. Looking at our transfer history, Kulu is the exception rather than the rule -- and would you be happy if he left for £60M now? 'Cos I wouldn't be.
Also, hopefully we'll effectively be getting £10M cashback when we sell Winks/Bergwijn to Everton. Unless they've pulled a "reverse Levy" by getting us to bump up the Richarlison fee and then pulling out of the Winks deal!
