This always happens with manager-types in business i.e. Barber and Burke. Some are worse than others though. The coach/manager e.g. Sami Hyypia, has to have the strength of personality and authority to deal with this and get his way. Not the tantrums of Gus Poyet or the dogmatism of Oscar...
I think our players were always a bunch of misfits. Just that Poyet and Oscar could glue them together a bit better.
No real success at building a cohesive unit.
Bournemouth seemed to have built a side and do not have any loan players.
