Correct me if I am wrong, but wasn't that money as 'cash reserves'? Which I think is something that usually you don't spend to sign players. Additionally, if I am not mistaken now we have more than 300m as 'cash reserves'.The problem with this narrative is that we had more than £150 million in the bank in the summer of 2011 (as we had had for the previous two years). It was there for SAF to spend if he wanted to - there's no other reason for keeping that much lying around doing nothing.
If I am not mistaken, until 2010 or so when we restructured the debt, we were actually at loss (higher spending than revenue) because of the large debt/interest payment and at some stage because of our failure to make the payment on time, the interest rate increased from 14% to 16% or so. So, despite Fergie's 'the money was always there to be spent' I think that there is something on the argument that we were skint on summers 2008/2009/2010, money simply wasn't there. At the same time, likely if Fergie would have been more aggressive about transfers, the Glazers probably would have found some money, be it from their other businesses, or by selling part of the club (similar to how they did with PIK 220m payment, and later a 62m payment which came from their own money).
