The loss against Doncaster Rovers was the Posh' third in a winless five-game run in the league, which has them just one point above Wigan Athletic at the foot of the table. Despite the poor form, Williams managed to guide Peterborough into the fourth round of the Carabao Cup for the first time since 2009 after overseeing a 7-6 penalty shootout win against Barnsley in a game that finished 3-3 just four days earlier. The Carabao Cup run is a rare highlight in an otherwise dismal season for the Posh.
The decision to sack Williams comes after a string of disappointing results, leaving Peterborough United in a precarious position in League One. The club will now look to appoint a new manager to try and turn their season around.
