Something pointed out to me I hadn't considered before this week - forgive me, I'm slow!! These players will be on chelsea's books and they will actually rarely pay many of them. Chelsea will insist on season long loans that involve, in many cases, payment up to the end of the season - not just game but actual end of the season so end of June - pay them when they're back at the club and then loan them out again within one or two months of their return. So, some players who've only been on loan and then been sold have hardly cost Chelsea anything and if anything only made them money as they've been sold for big money. Good business, bending rules or who cares?
