The former England captain, who now plays for DC United in MLS, began his career with the Reds’ Merseyside rivals Everton before moving to United.
However, despite his allegiance to the red side of Manchester, he is in no doubt about which team he hopes to see lift the Premier League trophy at the end of the season.
"It's a great reason to be out the country when those two are going head-to-head for the title," Rooney told talkSPORT.
“I hope Man City get over the line before Liverpool.
