If Sancho is available, honestly doesn't mean we can't sign him. Let's say if Sancho cost 100m, while Dalot is reported to go to PSG for 30m. That's pretty much 70m net.
I'm not sure why can't we sign young player with the potential to be WC with Glazer in charge with only 60m-70m net per year? Are you expecting us to sign 3 young player with potential to be WC per season? Because that's non-sense if you really think so. We signed Rio in 02/03, we signed Ronaldo in 03/04 and we signed Rooney in 04/05. None of them were signed within a season. At the end of the day it's step by step.
Prior Ole took in charge, our top problem was the poor recruitment & the strategy of the recruitment, we wasted all the money that was provided. Ever since Ole took in charge, the recruitment probably been the massive difference. We signed players who wants to play for the club, believe with the project as well as targeting young player with potential to be WC. Sancho is a young player with the potential to be WC, and ever since last season to now, all sources said he's been our main target.
Of course there is a limit of how much we can spend. However, I also believe we can exceed the limit if our top targets are available, this also be the difference that we are not being in rush in our signing and forcing ourselves to sign player that doesn't meet our profile/criteria just because we couldn't get the main target. We could sign Sancho last summer and exceed the 60m-70m net in one summer window, but we didn't because he wasn't available.
However, we did exceed this 60m-70m this season.
Maguire (80m), Bissaka (50m), Bruno (50m), James (15m) = 195m
Lukaku (70m), Smalling (2.5m Loan), Darmian (2m) Young (1.5m) = 76m
