Yeah Willian has been their best player this year, which isn't saying much, but he's quality. Even if he were to leave for lack of CL he would cost more than we would pay.
Not sure about Oscar, seems like a timid little player to me.
Well the market is incredibly inflated, and they payed 32 million for him two years ago...plus they got the money and won't let go of any key players, which in this kind of situation, he is.
But he's really not the type of player we need anyways.
