Manchester United are without right-back Rafael, who is serving a one-game ban after his red card last week.Fabio, John O'Shea and Wes Brown are all candidates to replace him, while Paul Scholes may figure at some stage. [LNB]Birmingham can call upon Cameron Jerome and Sebastian Larsson after both missed last weekend's derby with Aston Villa. [LNB]Ben Foster returns to Old Trafford for the first time since his £6m summer move, but defender Scott Dann has been ruled out for the rest of the season. [LNB][LNB]Manchester United[LNB]Suspended: Rafael (one match) [LNB]Injured/unavailable: Hargreaves (hamstring), Park (international duty), Valencia (ankle) [LNB]Birmingham[LNB]Injured: Dann (hamstring), McFadden (knee) [LNB][LNB] MATCH PREVIEW Under-par but still undefeated, the current Manchester United side may not be playing in the vintage style of some of teams built by Sir Alex Ferguson, but his current crop still look like the team to beat.[LNB] The Birmingham games in the last few years haven't produced a lot of goals. Hopefully we can change that trend. Our home form has been very good this season, and it has to be now. It's kicking on time Sir Alex Ferguson, Manchester United manager The club are only the seventh in top-flight history to remain unbeaten after 21 league matches, and it would take a bold person to bet against them making it 22. Birmingham's defensive strength has been undermined by long-term injury to Scott Dann, and the visitors also have one eye on next week's Carling Cup semi-final second leg against West Ham. [LNB]Among Birmingham's most recent line-up, only Stephen Carr and Barry Ferguson were alive the last time the club beat Manchester United 33 years ago. The Blues won 2-1 at Old Trafford in January 1978, and followed that up with an emphatic 5-1 home win in November of the same year. [LNB]In fact, 1978 is not only a landmark year for Birmingham, it also coincided with Alex McLeish's playing debut for Aberdeen, and subsequently the appointment of Ferguson as Dons manager the following August. [LNB]Ferguson has only ever been beaten five times in 65 Premier League matches by sides managed by any of his former players. McLeish, at the fifth time of asking, is dreaming of finally getting one over his former tutor, and with it ending United's unbeaten run. [LNB][LNB] MATCH FACTS Head-to-head[LNB]• The four previous Premier League matches between Sir Alex Ferguson and Alex McLeish have been tight affairs. Both games at St Andrew's ended in 1-1 draws, while United have edged both matches at Old Trafford 1-0. [LNB]• United have scored in every Premier League home match this season, while Birmingham have scored in seven of 10 away games.
