I actually think anything above 40 million should be a good sell. I like David Luiz and is my favorite player, but sometimes when you get an offer that is too good to be true you have to take it. Cause they never come back. Remember when offers came for Bosingwa, Kakuta, Essien, Kalou and such? But we never took it! Well sometimes you have to. I don't mean selling players on just the market, but above market inflated price as other clubs do to us.
