I saw all sorts being being thrown by our fans when we were up in that second tier at Old Trafford in the 2010 EFL Cup semi.
Programmes, bottles, one of the backs off a seat.
I think we’re just used to well behaved fans like Burnley, Wycombe and Port Vale etc. being up in our third tier and not had many trips from the likes of Liverpool so it comes as a surprise when they act like they do.
On the whole most big club’s sets of fans are the same or have a large minority of nutters. We're no different, we have loads of nutcases following us. Away fans often comment on us being bad for throwing coins into the away section at the Etihad. I don’t think we’ve won a derby or game against Liverpool at the Etihad without throng a blue smoke bomb into the away end.
Rio Ferdinand got a cut eye when a City fan threw a coin at him once.
