Michael Appleton's claim that his Oxford side have been the best team in League Two are "embarrassing", says Northampton defender David Buchanan.
Champions Northampton finished 13 points ahead of Appleton's side.
"Some of the stories about us being the second-best team in the league are embarrassing," said Buchanan.
"If you look through all the leagues from the Premier League right down to League Two, the biggest margin of victory is Northampton Town's."
He added to BBC Radio Northampton: "How people come out and say they're the best team in the league is a bit disrespectful to ourselves."
The Cobblers' promotion to League One was confirmed on 9 April and they were crowned champions a week later, while Oxford needed to wait until Saturday's 3-0 win over Wycombe to seal their place in the third tier next season.
Appleton's side, though, did reach the Johnstone's Paint Trophy final and FA Cup fourth round, and scored 84 goals on their way to promotion, more than any other team in the division, and lost only one of their final 10 League Two games.
The Cobblers finished their season on Saturday with a 2-1 win against Portsmouth, which meant they ended the campaign with an unbeaten run of 24 games.
"Oxford are a good side, but some of the things that have been tweeted and said I think are disrespectful to our group of players, management and fans," said Buchanan.
"We finished 13 points clear in a tough season. Show a bit of courtesy, we've been the best team in the league and that's it. We're having an open-top bus parade and we have got a trophy saying 'champions' on the bus."
