Bolton boss Gary Megson feels Birmingham's home comforts could prove crucial in the battle against relegation.
Wanderers have climbed out of the bottom three after back-to-back victories over West Ham and Middlesbrough, with Blues now occupying the final relegation berth in the tense scrap to avoid the drop.
He said: "When you look at the games Fulham, Birmingham, ourselves and Reading have got I think you would probably look and say that Birmingham are favourites because of the fact that they have got two home games.
"I know they got a poor result against Villa last week but I think one of the things they've got is a huge partisan crowd.
"I know very well from being in that part of the world and I don't think it's any coincidence the amount of penalties and free-kicks they seem to get at that place that have enabled them to pick up results.
"So I would say that Birmingham are probably favourites to get out of this because of the two home games."
Megson feels that the passionate St Andrews supporters could have a key role to play in the closing stages of the campaign.
He added: "If you look at the facts I think they have had six penalties this season.
"Birmingham's really are. I have taken teams there and it is a really difficult place to go.
"I think it follows if you look at the facts of how many penalties they get compared to other people and free-kicks around the box that when you look back are a little bit iffy."
