“It’s one of the things I don’t like about modern day football; it always seems to go on the manager’s toes and us players seem to get away with murder a little bit,” Coleman said.
“I think there is a lot of emphasis on teams doing badly. It’s something that I don’t agree with. I think managers need time and the manager here is working very hard.
“It’s not going to happen overnight or one season. He needs to get his own players in, implement his own style of play. That goes for all around the league. I think owners need to be a bit more patient.”
