Manchester United's claims that 'there's only one Ronaldo' have been met with a shirty response in Sao Paulo.
Fans of the legendary Brazil striker got a bit hot under the collar when they found out United were selling T-shirts bearing the Stretford End chant.
More than 1,200 readers joined an online debate on whether Cristiano or Ronaldo Luis Nazario de Lima was the greatest.
And the latter's new club Corinthians have designed their own jersey to remind the Barclays Premier League champions that 'O Fenomeno', then playing for Real Madrid, wrecked United's Champions League hopes at Old Trafford six years ago.
From Wednesday, £13 will get you a T-shirt proclaiming: 'There is only one Ronaldo that: scored three goals against Manchester United at Old Trafford; won three times the FIFA World Player of the Year award; won two FIFA World Cup titles; is the greatest scorer in FIFA World Cup history; had three unexpected comebacks.'
Corinthians have not confirmed whether the shirt will be big enough to fit Ronaldo, who still has some way to go controlling his weight judging by photos of his return to action last week following 13 months out with a knee injury.
