Former Manchester United captain Roy Keane has said he would throw his "medals in the bin" if he were a Manchester City player after the club was found guilty of all charges related to breaches of the Premier League's financial rules.
On Tuesday, the Premier League confirmed the Etihad club had been found guilty of flouting its rules over a nine-year period between 2009 and 2018 by creating "sham" contracts with commercial partners to secretly funnel more than £830m into their football operations.
City, who continue to deny any wrongdoing, won eight trophies, including three Premier League titles, during that period.
Keane said the achievements of City's players had become redundant because of the "cheating" that took place during that time.
"If I was a player, I'd be 100% sticking those medals in the bin. Of course you would, it's cheating," Keane told ITV Sport ahead of England's match against the Czech Republic.
"They won it on the pitch because cheating was going on."
And on the club he added: "They knew it would hurt a lot of people, but they've still done it."
Keane's former United team-mate, Wayne Rooney, however, says his former club do not deserve to be awarded Premier League titles if their city rivals are stripped of them as punishment.
Sanctions are yet to be announced and City plan to appeal against the decision.
One possible punishment could be the club being stripped of top-flight titles. They have won the Premier League eight times since Sheikh Mansour's takeover in 2009, three of which were in the period when they were accused of breaking financial rules.
Rooney was part of the United side that finished runners-up to City in 2011-2012 but does not want to be awarded the title retrospectively.
Speaking on the Stick to United podcast,, external he said: "I wouldn't feel comfortable about accepting another Premier League medal if I'm being honest, because I don't think we deserve it. We didn't do enough that season to win the league.
"I'm thinking as their players, they're there doing everything they can to win the Premier League title and in their minds they've done it.
"And, if those players have got no understanding of what's going on above them, then if that happened to me - if all of a sudden Manchester United have been doing the same and I'm getting my Premier League medals taken away from me - I'd be absolutely devastated.
"They might take them away but I wouldn't want it because I don't feel as a team we deserved it that year because we obviously didn't finish first."
Rooney's former United team-mates Rio Ferdinand and David de Gea both posted on social media after news of the guilty verdict emerged on Friday, suggesting they should be awarded retrospective title wins.
And former Stoke City boss Tony Pulis said he felt "cheated" after his side were beaten by the Blues in the 2011 FA Cup final.
"When I've heard of ex-team-mates and people saying, 'we've won another medal', I'm happy with the five I've won," said Rooney.
"I wouldn't want this one just sat there... 15 years later or whatever it was you get a medal because City cheated. I wouldn't feel comfortable.
"The question is, would I want to receive that medal for finishing second? No.
"Some players might. I just wouldn't feel comfortable for accepting a Premier League medal for finishing second."
While Rooney is against titles being taken away from City, he does believe they should be relegated.
"I do think we're going to see City getting relegated," said the 40-year-old. "However that happens I don't know but I think we're going to see them get relegated."
Rooney added: "I'd put them in the lowest league they can go in and then put restrictions on them in terms of how much money they can spend for the next three or four seasons.
"If you're just putting them in the Championship, and I get that's a massive punishment, they're going to come back up. Where, I feel if they have got restrictions... League Two, whatever... that could be very difficult for them.
"For instance, if they got a 20-point deduction for the next three years then players won't want to stay there. If it's Championship for a season, you could talk players round.
"I'd go as big as I can really."
Earlier this month, Pochettino said Chelsea should be stripped of the 2016-17 Premier League title after being found guilty of historical rule breaches and that it should be "awarded" to his Tottenham side, who finished runners-up.
Sources have told BBC Sport that other top flight clubs are seeking legal advice over possible compensation claims following the decision against City.
City were charged by the Premier League in February 2023 following a four-year investigation.
The club were referred to an independent commission. A behind-closed-doors hearing began in September 2024 and ran for about 12 weeks.
"Where were the controls?" said Pochettino on City being found guilty. "That's what gets my attention. Where were the controls?
"If I remember being at Southampton, then Tottenham - I remember building [the Tottenham Hotspur Stadium] and not having the economic possibility of a transfer for 18 months.
"I think we were the only team in the history of the Premier League with 18 months without [making a transfer].
"Tottenham was fighting for titles with those above us and every year in the top four, getting to the semi-finals of the Champions League without being able to do a transfer for 18 months, all because we needed to get used to the [Premier League financial controls]?
"They were so strict with us but also so lenient with others. Because of that, that's why I say: it's all very strange."
On Tuesday, La Liga president Javier Tebas said he agreed with Pochettino and believes City should face the most severe sanctions possible after an "era of disappointment".
"In my opinion, the most severe sanction provided for under the Premier League regulations should be applied," Tebas, 64, told BBC Sport at a summit in London hosted by global players' union Fifapro.
"Given the number of years involved, the repeated breaches, the denial and the lack of cooperation, the most severe sanction allowed under the Premier League rules is what should be imposed, although I do not know exactly what that sanction would be."
