No one is doubting the expectations but there is balance to every argument. If what you say is so critical to investors like Silver Lake why didn't we buy Laporte and Van Dijk, why didn't we stump up the additional funds of Sanchez or Maguire or Jorginho, why didn't we compete for the signatures of the likes of Neymar and Mbappe.
I think what you're proposing is one of those nice in theory, but could go horribly wrong in reality. I'd love to see Tosin, Eric and Taylor all get their chance here to really prove themselves, but Taylor only stepped up from the u18s last season, I think he needs either a year solidly in the EDS with cup and occasional league minutes, or a loan to the Championship at a club where he's got realistic chances of starting regularly.
As for Tosin, I think he's great and improved but if we're going into next season with him - 2 years championship experience (both in relatively mediocre teams) as our starting RCB, I am worried against the big sides. I think if he were to agree say a loan to an Everton or even Wolves at best, and have one year in the PL at a non relegation threatened side, he could really kick on and prove if he's good enough for us. Maybe even Celtic, especially for the European exposure whether EL or CL.
And Eric, my personal favourite of the three and what he lacks in physicality he does make up for in passing and grit and effort, which does make him an especially good partner for Laporte. Barely any mistakes and largely had his blushes saved when he has, and I think he's ready to be the first name on the bench/first rotation CB. A year with pretty regular game time in all comps could transform him, especially if he could put a bit of muscle on too.
I do think this points to needing a top CB who's a bit older, to give space for these young guys to take over if they prove good enough. Koulibaly is literally the perfect choice. At his peak, still looks fantastic and a level above our current slate of CBs besides Laporte. VVD, Ramos, Laporte and Koulibaly (in no order) are in my eyes the top 4 CBs in the world. Having two of them starting for us would be transformational.
