yes there is less to spend but you are also assuming we will need to make lots of signings we don't 3 or 4 maximum this summer, players like Chilwell, Maddison, Maguire & Barnes will improve themselves which will improve the side without needing a signing, yes Monaco apparently want £40m for Tielemans but they also want Adrien Silva so there is a deal to be made there.
There are also a number of high earners like Fuchs and Shinji coming off of the wage bill freeing up funds and it wouldn't be unreasonable to think Wes has taken some form of reduction to match his reduced role in the side.
Yes we have got the training ground to pay for but that was what the loan we took out was for, as I understand it, to reduce the drain on resources whilst its being built, also and this is the main point, the owners have always spent heavily and given no indication of that stopping
