Manchester United midfielder Facundo Pellistri has enjoyed a dig at Manchester City fans ahead of Sunday's derby.
Pellistri admits he rarely sees City shirts worn around Manchester.
"Manchester is all about Manchester United," the winger told Carve Deportiva radio. "You don't see City shirts or flags.
"Sometimes, with my girlfriend, we go out and say 'let's try and find one', and we don't see them."
City manager Pep Guardiola responded yesterday, smiling: "I will speak with the Puma department and say 'what's happened with the shirts?'
"It's okay. If this guy, and his girlfriend believe that, it's fine."
