you're thick, it doesn't matter what the players want. they signed contracts and have to abide by them, end of story. we can choose to sell, we chose not to.
Look at suarez, same situation, 40m arsenal handed in request and was turned down. went for 75m to barca.
mate you will be happy with this decision next summer when he goes to barca, psg, real, bayern, etc for 40m+ and chelsea are left in the dust by their buying power and CL success. You'll get even more money and buy your way up to the championship.
