Former QPR goalkeeper Paddy Kenny has enjoyed winding up Manchester United fans.

Kenny, 44, took aim at United supporters with a dig about Wayne Rooney's age after the Old Trafford legend questioned how Manchester City won the Premier League title in 2012. In an interview a decade on from that extraordinary day at the Etihad, old Wazza questioned the manner of City's dramatic final day win.

"Paddy Kenny should have done better for a couple of the goals," Rooney, 36 suggested. "City get the second goal and QPR kick it straight back to them and that's never been questioned - I find that strange."

Kenny initially responded with a tweet comparing how he and Rooney look now versus their respective ages, drawing significant blowback from United fans.

"36 v 44 Rooney must of (sic) let that Aguero goal get to him," the former Republic of Ireland stopper wrote next to a picture of himself drinking a beer and Rooney sporting a beard.

Kenny doubled down on his trolling of the Red Devils in a later tweet, saying: "I've lived in Man Utd fans heads all day rent free."
