Two things! firstly, Hughton will most likely not be at Birmingham next season & secondly, do you really think Ben Foster will drop down to the Championship after the season he's just had? come on Wilma get real
Where is he going to go ? Albion do not thinks so he has said no / been overlooked before by the club. he like everyone else has read about Raneiri, wilkins the german chap etc all being interviewed for the job. now taking that into account what makes you think he would consider any approach for him. even if which i doubt BCFC gave albion permission.
Norwich Swansea he would be on a hiding to nothing with either one of those clubs.
What you have to take into account is Hughton knows what is happening at Blues,
he knows if the potential new owners rumours are true.
He knows the financial state of the club and how the embargo will affect his squad next season
He knows if any players will be sold.
He knows the potential of the club
Now if he was not 100% happy with any of the above he has had ample opportunity to resign. and apply for the albion job.
Foster is under contract at BCFC and if you read the reports he never wanted to go to albion and if i remember correctly he told Colin Tattum that he would play in the championship, but Blues wanted him to go on loan to preserve his value. and save his wages.
