Birmingham City boss Alex McLeish has urged fans to get behind midfielder Sebastian Larsson.
The want-away Swede was jeered by away fans during defeat at Manchester United.
McLeish said: "The stick Seb got was disappointing. I would like to think the fans will not jeer Seb.
"It is the way football is in the modern day. I don't think there is a great desire for Seb to leave the club but he has got to do what is right for him and his family.
"We must respect that and I'd love the fans to give him a rousing reception if he is playing.
"I've worked with guys on the verge of a Bosman transfer before and they down the tools - but Seb wants to play football.
"He has made that clear to me and it lets him escape from the madness that is surrounding his contract talks and the future."
