Mate i think you don't like maicon and that the reason you don't rate him. You claim that you've seen many games for him but i "really really" doubt that you've seen that much of him in the past years (or again you've seen him but you just don't like the guy, it happens).
Maicon was 3rd highest assists in the league last season (4th the season before that) and for a fullback to have that many assists is pretty incredible. And i know like many people who don't really follow serie A one can jump on the wagon and say well serie A is shit (i've heard that many times before specially from those who don't follow the league) but i will go along on that assumption. If maicon was soo overrated and shit then why does a club like chelsea and specially Real madrid who can easilly sign any player in the world would want such a shitty player ?!! Not to mention that he is a starter in the brazilian squad ahead of a player like Dani alves who was brought by Barca for about 30 mil euros, don't you think there is a reason for that !!
It wasn't just he's agent that was saying that Madrid wants him but even Moratti in an interview few weeks ago said that he thought madrid wanted Zlatan but they were really after Maicon and that they would like to have him but till now the only club that offered an official offer is "Citizen".
Believe me when i say i absalutely hate overrating players but maicon deserves the hype around him. It's not just he's talent but he's workrate is incredible. Since he's arrival to the team he was the most dynamic player. Works as hard as 2 players combine.
I'd be definately sad if he left the club, he's by faar my favourite player in the team but i'd much rather see him playing for City than clubs like Madrid, chelsea or United.
