Nigel Pearson took aim at Michael O'Neill after the Stoke boss apparently told his players Bristol City "were the worst team in the league."
The Potters became the third club that City completed the double over this season after Cardiff and Reading when Jay Dasilva scored a late winner at the bet365 Stadium on Good Friday.
In the reverse fixture back in November, the Robins won by the same scoreline when Tyreeq Bakinson scored the only goal of the contest to ensure City's second home win in 20 games.
Stoke sit nine points above City in the table having had an underwhelming season themselves after falling out of play-off contention.
Despite failing to pick up a point against Pearson's side this season and becoming the first side not to score against City over two matches, it seems O'Neill was far from complimentary about the club to his players.
After the draw against Sheffield United on Monday, Pearson couldn't resist taking a dig at Stoke after being asked about the difference two games can make following the 1-1 draw with Peterborough.
He responded: "Have you seen Peterborough's results recently? They've got seven points out of nine. I keep saying don't always look at the table there are no mugs in this division.
"Absolutely no bad sides apart from apparently Stoke's manager told his players and staff we were the worst team in the league so that's quite interesting and we've beaten them twice so make of that what you will."
Later in the press conference, he made another sly jibe by adding: "Today we worked hard, against a decent side who certainly moved the ball a lot quicker than Stoke."
Pearson, who was a coach at Stoke for two years in 1999, appeared almost sympathetic towards their opponents after the victory on Friday by saying they would be "pulling their hair out" at losing the match.
He said: "We talk about personalities and I think we showed that in abundance today, it was a collective effort, a bit gritty, it had to be against a side that have got quite a bit of quality.
"They must be pulling their hair out. The two games we've played against them they will think they could have won both. We've had that feeling many times this year."
O'Neill is aided by former Bristol City manager Dean Holden who recently revealed his determination to get back into the dugout in the future following his 41-game stint at Ashton Gate.
