Queens Park Rangers' outspoken midfielder Joey Barton believes Manchester United legend Roy Keane was not as good as Liverpool captain Steven Gerrard.
The 31-year-old tweeted: "On a serious note. Gerrard for me, was better than Roy Keane. At one stage he was up there with the best midfielders in the World.
"Lucky enough to have Played against them both on number of occasions. Steven Gerrard streets ahead [in my opinion]. Keane was v good but SG better…
"People forgetting Keane played with the best in the World at United. He wasn't same player with the Republic. Was he?
"[Keane] was a World class leader. Winner. Competitor. No doubt about it. No doubt a World class player. Just that Gerrard was better. #keane #imo"
Keane captained the Red Devils during one of the most successful periods in the club's history, and walked away from Old Trafford in 2005 having won seven Premier League titles, four FA Cups and one Champions League - although he missed the final of the latter, in 1999.
Gerrard, in comparison, is still playing for Liverpool but has won two FA Cups, three League Cups and a Champions League winners' medal.
Both have been fiercely competitive leaders for the Premier League rivals - but even though Keane has won more silverware, is Barton right to claim that Gerrard is a better player?
Keane hit the headlines earlier this week after Sir Alex Ferguson criticised him in his recently-released autobiography, but Barton believes the ex-Manchester United manager had made a "right mug of himself".
I know Fergie is trying to sell his book but he's making a right mug of himself with statements like that an slagging his former players off," Barton added. "Did he really need the extra few bob a book will have raised?"
