Years of underinvestment has brought us to this.
We've seen scholes, giggs, Hargreaves, tevez, Ronaldo, fletcher, Ferdinand and vidic leave/been chronically injured or retire over the last 5 years and we've replaced them with Valencia, young, Cleverley, Fellaini, Smalling, jones, Anderson to name just a few.
World class players going out, cut price (or in fellaini's case, just shit) players coming in to replace them. We are now trying to put all of that right in one window. We won't spend like this again for a long time. It'll be back to 25-40m net spend per window.
I fairness to the club, Nani and Anderson had the potential to be great signings for the club. But Fergie also bought some real shit.
