The club is trying to be self-suficient. There has been too much wasteful spending, no more are the days where the club will drop an obscene amount of cash on players like Cuadrado. This isn't new, the club is very methodical and slow in the transfer market. People still think that Chelsea are a spending machine like United or City but that hasn't been true for years, big money does get thrown around but to the extent of those two clubs.
