Manchester City chief Brian Marwood admits they offloaded one player over discipline problems.
Marwood revealed that at least one player had left City after showing disrespect.
"A player no longer at the club came out of the reception at our Carrington training ground, where we'd spent a lot of money, and spilled some rubbish on the pathway. He then walked across newly-laid turf - which shouldn't really have been walked across - and got into his car. He disrespected the environment he was in.
"Five minutes later, Gareth Barry came out, picked up the rubbish and put it in a bin. It said something about the values and behaviour we must deliver to young players."
