The best league in the world is the spanish league, followed by the premiership. Mata is good enough for the spanish league, so obviously good enough for the premiership.
Not sure if he is a star or not, but looks decent, he's young and will improve, and better than any winger we have at the club.
i premiere league is best then followed by spanish league...there are only two good teams in spanish league but in BPL there are 20 very highly competive teams.~~~
