They would, probably a lot more than that.
This was me saying we could have had those 3 when I mentioned them for that sort of combined fee.
I think you are spot on mate. Bailey in particular looks to have really kicked on. We were also close to Son in summer 2016 free he hasn't settled at Spurs and we looked at D Grey when he had the release clause around 12 million pounds.
On the advise of Koeman and under the guise of "proven Premier league players" we spent similar money on Sigurdsson & Schneiderlin and Klaassen (who to be fair I didn't view as an awful signing just one that hasn't worked out).
Whats clear for me, is Steve Walsh has a great eye for a player but doesn't seem to have the confidence and skills to close deals. When you look at the list, Son, Grey, Ndidi, Mahrez, Kante, Vardy, Bailey, Isak, Lookman, Vlasic, Gueye etc you see a guy who has an adept eye for locating talent. We would be better served backing his judgement and finding a coach to utilise his skills. I also think we need a DOF above him to work more at te squad management, maneger interaction, and overarching questions he struggles with.
