As much as I like Bullen as a coach and person, I honestly don't think he has it in him at Championship level.
He has succeeded whilst caretaker for the few games after someone has gone and ultimately it fades as effort and confidence wanes due to woefully lacking tactics and guile. He could not do it before, and if he is still 'in charge' with coaches behind him or not, it is likely to get worse culminating in another Burton type no show later in the month as the players lose faith in what they are being asked to do.
Chansiri is the man who decides and it is about time he took control and gave himself [and the players and us] a chance of recovering after as a good a start as we could have expected without an experienced manager.
It won't be long before we are playing catch up again which ultimately leaves us short this season - he won't have another opportunity to 'sell' the stadium again next year.
Dejphon - you standstill, you go backwards - get someone experienced in man and give yourself a chance.
