Wayne Rooney has subtly mocked Liverpool for their lack of Premier League title trophies, after the striker took to twitter to stir the notoriously partisan rivalry between Manchester United and Kenny Dalglish's side.

Given the recent well-publicised guilty charge levelled against Luis Suarez for his alleged racist comments towards Manchester United left-back Patrice Evra, and the fact Liverpool moved to discredit the Frenchman's credibility via a public statement, the animosity between British football's most successful clubs remains intense.

United face Liverpool on February 11th, and the game is already set to be one that will create a great deal of tension, and Rooney had a small dig at the Red Devils' rivals by claiming to only have just realised that Dalglish's team haven't won the top tier title since 1992.

"Anyone know when the Premier League started. What year," he wrote on his twitter account.

Upon receiving the answer from one of his 2.3 million+ fans, he responded: "Thx. Looks like 1992. Man United. Arsenal. Chelsea. Blackburn only 4 teams won it. Wow. I thought Liverpool had won it?"

While Liverpool have been both vocal and visual, the Reds wore t-shirts in support of their striker prior to their match against Wigan, in opposition to the recent eight match ban imposed on Suarez, Manchester United have refrained from commenting and instead have maintained a dignified silence to date.

Liverpool's wearing of the aforementioned t-shirts has been widely derided as an irresponsible gesture given the severity of the allegations, while some questioned the evidently emotive statement they released immediately after the FA's punishment of Suarez.

Liverpool could only muster a draw at the DW Stadium, while Manchester United thrashed Fulham 5-0 to maintain the pace on leaders Manchester City.

Rooney's comments may or may not have been a direct dig at Liverpool, but Manchester United's fixture against Kenny Dalglish's side on February 11th at Old Trafford promises to be an engaging if hugely hostile affair.
