BBC Sport - Sean O'Driscoll's Nottingham Forest sacking strange - Birtles Former Nottingham Forest striker Garry Birtles has called the sacking of manager Sean O'Driscoll "strange." The 55-year-old was relieved of his duties at the City Ground on Boxing Day, just hours after leading the side to a 4-2 win over Leeds United. Sean O'Driscoll - July 2012 to December 2012 Steve Cotterill - October 2011 to July 2012 Steve McClaren - June 2011 to September 2012 Billy Davies - January 2009 to June 2011 Colin Calderwood - May 2006 to December 2008 Gary Megson - January 2005 to February 2006 Joe Kinnear - February 2004 to December 2004 Paul Hart - July 2001 to February 2004 David Platt - July 1999 to July 2001 Birtles told BBC Radio Nottingham: "It doesn't make any sense. You need stability and continuity. The players had just got used to Sean and the way he wants to play, sacking him now just seems strange. He added: "I can't believe the timing of it. Sack him at the end of the season if it hasn't worked out. He had got them in a good position and they looked like they were challenging. There's a lot of questions to be asked. The former Doncaster boss was appointed manager by the Al-Hasawi family on 19 July after they sacked previous incumbent Steve Cotterill just days after taking over the Championship club. Victory over Leeds left Forest just one point off the play-off places but was not enough to see O'Driscoll keep his job. Chairman Fawaz Al Hasawi revealed on his Twitter account on Wednesday night that he had already spoken to a "Premier League manager" and had arranged a meeting for Thursday. Birtles does not think that replacing the manager at this stage of the season will lead to an upturn in form. "The problem they have now is a new manager is going to come in with new training methods, new background staff and a new way to play on a Saturday afternoon," he continued. They might bring in a load of new signings and then they'll have to gel together and that isn't always easy and takes time. Forest take on fellow promotion hopefuls Crystal Palace on Saturday before travelling to Blackburn, who sacked manager Henning Berg on Thursday, on 1 January.
