Could be just some elaborate rumour, however if we did get offered £57mil for Oscar why on earth wouldn't we accept it? Could easily invest in a better number 10 with that kind of money.
Obviously a lot of other factors to consider such as Oscar actually agreeing to personal terms etc.. but even so, I believe Chelsea are crying out for a new number 10.
