Do you mean Les? This was / is our strategy.
BTW not sure anyone is mentioning 'world class players' but players who can be acquired relatively cheaply, do a good job for the club for a couple of seasons then move on for significantly higher value and repeat. Supplemented by developing youth and the occasional 'exception' such as Pelle. In the absence of a middle-eastern or similar beneficiary there aren't so many other options if you want to stay in the Premier League.
