Manchester United's striker Sergio Aguero and defender Marcos Rojo are embroiled in a bitter dispute even on the eve of the club's derby over a past row involving Aguero's girlfriend.
Aguero pulled out of a kids' coaching session on Friday in the East Manchester district of Ardwick because Rojo was a part of it too. The session was a part of the Premier League Kicks initiative, reported The Mirror.
The striker left at the last minute claiming that he had to pick up family members from the airport.
A bitter feud cropped between the two during the World Cup when Rojo invited the ex-husband of Aguero's girlfriend, Karina Tejeda, into Argentina's dressing room to celebrate the team's win over Nigeria.
Rojo said he would mark Aguero in the match "with a degree of firmness.
