The trouble is... And why everyone is so upset about even the possibility of him leaving... is that he's the ideal professional footballer. He's a PR dream, and not just because he communicates with the fans. Where someone like Rooney has drinking and smoking problems, Mata spends his weekends blogging, reading, listening to music, and exploring London. And that's not even mentioning his football talent. He's maybe the most cerebral player in the league. His ability will probably age like a fine wine. Roman, Jose, whoever is listening: KEEP HIM.
