Manchester City's unbeaten home record in the Premier League is already showing signs of being broken this season.
The reigning champions last tasted defeat in the competition at the Etihad Stadium in December 2010, but were made to work hard for their 3-2 victory against Southampton on the opening day of the 2012/13 campaign, and did even better to avoid defeat in last weekend's closely contested 1-1 draw with Arsenal.
Now, in the aftermath of last night's shock Capital One Cup defeat at the hands of Aston Villa, Roberto Mancini will be determined to get back to winning ways as quickly as possible.
City return to action when they travel to Fulham on Saturday, before hosting Borussia Dortmund in the Champions League on October 3. Three days later they entertain Sunderland - the next time their Premier League record will be put on the line.
Restoring confidence and belief amongst his Citizens players will be Mancini's number one priority. But, before the risk of their impressive run ending, GiveMeFootball takes a look at some of football's most impressive home records.
Liverpool: 21 consecutive home victories
Under the inspirational management of Bill Shankly, Liverpool's run began with a resounding 4-1 win over Crystal Palace in January 1972 and ended when they drew 1-1 against Derby - the team they would dethrone as champions, 12 months later.
Manchester United: 12 consecutive home clean sheets
In April 1994, the Red Devils conceded their last goal at Old Trafford in the Premier League for 18 hours and 48 minutes when Oldham's Graeme Sharp bagged a 70th minute consolation for the Latics.
12 games later, Sir Alex Ferguson's incredible defence was finally breached by Nottingham Forest striker Stan Collymore, who curled a superb long range effort into the top corner, inspiring his team to a memorable victory.
Real Madrid: 49 home League games unbeaten
Stretching over three seasons, former Los Blancos boss Vicente del Bosque enjoyed a 49-game run in La Liga without defeat. It came to an end in spectacular fashion just days before a crucial Champions League semi-final tie against Juventus in May 2003, when they were thumped 5-1 by a Samuel Eto'o inspired Mallorca.
Chelsea: 86 home League games unbeaten
Jose Mourinho oversaw a majority 60 of Chelsea's 86 league games where they avoided defeat at Stamford Bridge, with Claudia Ranieri, Avram Grant and Luis Felipe Scolari also involved at some stage too.
Jose Bosingwa's own goal gifted Liverpool a 1-0 win against the Blues in October 2008, the first time the west London club had tasted defeat since Patrick Vieira and Edu scored in Arsenal's 2-1 win against Chelsea in February 2004.
Jose Mourinho: Nine years unbeaten at home
Spread over a quartet of top European clubs, the Special One's incredible 150-game unbeaten record in home league games came to an end with defeat to Sporting Gijon in April 2011.
Mourinho hadn't lost a league game on home soil since his nine-man Porto side lost 3-2 to Beira-Mar in February 2002, going unbeaten for his entire stints at both Chelsea [2003-2007] and Inter Milan [2008-2010].
