Manchester City fullback Aleksander Kolarov rates their clash with Manchester United as the 'friendly derby'.
The Serb claims the Lazio-Roma and Red Star Belgrade-Partizan Belgrade derbies are fiercer.
"In Manchester, there is more humour," Kolarov told the Daily Telegraph. "In Rome or in Belgrade, it is different. Here, the fans just want to win, but they don't think bad.
"The fans just want to support their teams to the maximum and this is good. I like this."
