Rio Ferdinand may have left Manchester United this week – but he still seems to take the derby rivalry seriously

The former England captain was in Singapore on a promotional tour with Manchester City and Argentina star Sergio Aguero. City may have had the upper hand over their neighbours this season, but there was no lack of competitive spirit when the pair went head-to-head in Asia. Ferdinand jetted off to Singapore hours after being told in the dressing room at Southampton that his Manchester United career was over, while Aguero flew from City's post-season trip in Abu Dhabi after meeting the club's owner Sheik Mansour but will miss Thursday's friendly with Al Ain in order to take part in the promotional tour
