Diego Costa's ridiculous Chinese Super League option

This one comes courtesy of Duncan Castles for the Sunday Times (who are on a roll today with the whole doping scandal story, too).  Castles tends to be good with Mourinho things.  How good is he with Diego Costa things?  I guess we'll find out.  (Or we won't, as it's often the case with transfer rumors.)

Chelsea are to be offered €90m (£72.1m) to sell Diego Costa to the Chinese Super League this summer. Two clubs from the Asian league have signalled their intention to invest a continental record transfer fee to the unsettled Brazil-born striker's representatives.

Such an offer would blow out of the water anything the likes of Atletico Madrid or even Paris Saint-Germain could offer for the striker.  Of course, as we saw in Oscar's case, just because there's an offer, it doesn't mean that it has to be accepted by the club or the player.  Then again, that's why CSL clubs are offering such outrageous fees and salaries (the offer would supposedly include 2x Costa's current salary), to entice the unwilling to make the jump.

While other rumors continue to claim that Costa wants to stay and that Conte wants him to stay, our leading goalscorer now has a few more potentially tempting options should he want to make his Chelsea exit after just two seasons.  The Times' story posits that in such a case, Cheslea would use the proceeds from the sale to try to tempt Lukaku back for around £60m.  Wow!
