Bet365 have opened a market on when Manchester City's next clean sheet will come after Joe Hart conceded again on Saturday.
Roberto Mancini's side are now 13/8 favourites to retain their Premier League crown and 20/1 to remain unbeaten during the 2012/13 campaign.
But their defensive displays have been anything but certain so far and they failed once again to shut out the opposition in the 2-1 victory over Fulham at Craven Cottage.
When will Man City keep their next clean sheet?
Borussia Dortmund (h) 3 Oct: 7/4; Sunderland (h) 6 Oct: 6/4; West Brom (a) 20 Oct: 6/1; Ajax (a) 24 Oct: 12/1; Swansea (h) 27 Oct: 10/1.
No clean sheet in above games: 14/1
2012/13 Premier League outright:
Man City: 13/8; Man Utd: 2/1; Chelsea: 3/1; Arsenal: 10/1; Spurs: 40/1; Everton: 66/1.
Man City to remain unbeaten in Premier League during 2012/13:
Yes: 20/1; No: 1/66.
