Last season, Sunderland were renowned for being a well-drilled and organised side, with onlyArsenal,Manchester CityandBrightonconceding fewer goals.
But Regis Le Bris' side have now let in 17 goals in just nine games in this campaign.
That helps explain why they have won just a single league game so far - against Fulham on 30 August.
They definitely miss Dan Ballard in their back line, with the defender out since late September due to a hamstring injury.
But they continually make errors, as proven here with Coventry's first two goals - and centre-back Omar Alderete will now be suspended for next week's clash withChelsea.
They did at least show some more attacking threat here with 17 attempts on goal and more possession that their opponents, but it was not nearly enough.
