#3 Chelsea FC 03/10/2007 to 02/04/2008: 686 minutes

2012 Champions League winners, Chelsea, during the 07-08 season managed to not concede a goal for 686 minutes from October to April. Jose Mourinho just got sacked as Chelsea boss sometime in September 2007 and was replaced by Avram Grant who went on to guide Chelsea to their maiden final and this record.
Four Champions League group stage games against Rosenborg, Valencia, and two against Schalke, followed by the round of 16 ties against Olympiacos and the English side didn't concede a goal. With Cech in goal, Ivanovic, Carvalho, Terry, and Cole in defence, the club's defensive setup was a formidable one.
The club conceded finally to Fenerbache in the quarter-finals but got through and went on to beat Liverpool in the semi-finals before losing to Manchester United on penalties in the final. Grant enjoyed more than half a season in charge of the Blues before being removed as manager after the CL final defeat.
