Madrid have a habit of getting the players they want by offering huge wages and letting them run their contracts down. Unless he wants to go there, we should match the wages imo.
Frank didnt rate him that much- but I've seen a few hundred players at Stamford Bridge and he is a rare breed. His leadership, aggression, getting in someones face, getting us going in the ground is invaluable. He plays with the same win or die of Diego Costa and contributes in a hundred ways the stats sheets just don't capture.
