As UEFA Champions League debuts go, Leicester City's looks like it will take some beating. Not only have they qualified for the round of 16 as Group G winners and with a game to spare; they have conceded just once in doing so.
Teams to go an entire group stage conceding only once*
2010/11: Manchester United
2015/16: Paris Saint-Germain
Claudio Ranieri's Premier League champions now need to keep a clean sheet at Porto on Wednesday 7 December if they are to join this exclusive club. Should they manage it, they will be further encouraged by the fact that four of the teams listed went on to reach the final. (Chelsea and Liverpool both conceded only once while in the same group.)
No side has made it through a UEFA Champions League group stage without conceding a single goal.
*No team ever let in just one goal in the second group stage, which was in existence from 1999/2000 to 2002/03 inclusive.
