Oscar is a decent crosser of the ball but I wouldn't say the best in the squad, that clearly goes to Hazard. You're just saying that because he whipped some great balls in in the Brazil game but that's just short term memory...Regardless, I like Oscar in the middle and Willian out wide. Oscar always tends to drift out wide and Willian tends to drift in anyway, so it complements the team as a whole as it does themselves too.
