I think we overrate our 'advancement' in signing ability if we are using Solanke, Maddison and MVDV as examples. Firstly, i'm not sure we were beating the likes of Arsenal, Chelsea, Man Utd etc to those signings.
Secondly, this last summer we NEEDED to sign more than one immediate first-teamer and we didn't.
Thirdly, it's not as if we haven't signed such players before, i.e. signings from lower-level PL clubs for whom we are a step-up. It isn't anything novel, certainly no different to pre-stadium transfers.
So on the evidence of that, i'm not sure much has actually changed. If in the last transfer window (when there were clear needs if we wanted to step-up from last season) we had signed two or three immediate first-teamers of the kind of profile of Solanke, Eze, Neto etc (to use as examples, due to profile, how much they'd improve the first team and age/experience) alongside the likes of Bergvall etc then i'd look at things differently.
But on that basis, i see no difference as i say to pre-stadium transfers and so i wonder why people think we are 'more attractive' to players than we used to be...surely if we were, we would be taking full advantage
