At what he offers yes, but not at what he/they offer the team in general then not a chance. Sensational footballer without a doubt not denying that, but as we have seen i'd rather Oscar and Hazard any day of the week. Offer far far more and in my opinion Hazard could become something really special.
Depends on what team it is. In terms of Chelsea, maybe not. Regardless of what Hazard might become, there can be no denying that at the moment Mata is still a superior player to him and particularly Oscar, who's been no great shakes creatively this season.
There's a huuuuuuuge amount of trying to downplay Mata in this thread, and funny to me though it is, the sooner everyone stops doing it the sooner we can all move on. Otherwise everyone's just going to keep taking the ****; justifiably so, I'd say!
