Has to be Bobby. He changed our mentality, got us to the champions league, tore that banner down, the 6-1, the 1-0 at home against that lot, the fa cup semi final and final, the league title and of course got us Balotelli. He will forever be a legend and a hero in my eyes. Also enjoyed the days of Keegan (used to write into the club as a kid when he was there and I would always get a signed picture of Keegan back although it was never what i actually wanted, must have about 10 of the bloody things).
