Wayne Rooney rips into former Manchester United teammate for this Liverpool post

Wayne Rooney might not be having the greatest of times on the pitch right now, but he's still having a bit of craic off it.

The 31-year-old England captain has apparently not even travelled down with the team to Stamford Bridge for Manchester United's crunch clash against Chelsea on Sunday, despite regaining his place in the starting line-up against Fenerbahce in the Europa League. But his dip in form aside, it's not dented the old Rooney wit in the slightest. Rooney still found the time to have a cheeky dig at former United teammate Michael Owen on Twitter. The ex-United and Liverpool striker shared a post as he watched his former club secure a vital 2-1 win over West Brom at Anfield to put them on level-pegging with Arsenal at the top of the league. "Come on Red Men. A win by two goals and it's 'top of the league'" he tweeted out during the game, which saw Liverpool's Sadio Mane and Philippe Coutinho give them the victory. But Rooney obviously wasn't impressed with the former Red Devil egging on their North-West rivals and tweeted him to question his allegiances. "Interesting this Michael I thought you was a united fan???" quipped Rooney who played alongside Owen at United under Alex Ferguson. https://twitter.com/WayneRooney/status/789886103847329792 Owen famously crossed the divide and joined United on a two-year deal in 2009, five years after his eight-year spell at Liverpool came to an end. It was at Old Trafford where the ex-Real Madrid and Stoke man won his first and only Premier League title in the 2011-12 season. Despite rising to prominence at Liverpool, where he scored 158 goals in 297 appearances, and playing at the Bernabeu, he called United 'the biggest club in the world'. No wonder Rooney was heckling him on Twitter then. Owen, who works as a pundit for BT Sport, has returned to Liverpool as the club's first official international ambassador.
