Former Manchester United striker Diego Forlan has indicated Luis Suarez is still uncertain about his Liverpool future – and revealed he has told his compatriot to consider a move to Old Trafford.

After a summer of uncertainty where his future at Anfield looked as if it may be coming to an end, Suarez has gone onto enjoy an incredible campaign for the Reds where he has proven to be the catalyst behind the club's title push.

After rejected bids from Arsenal in the summer, the Uruguayan international ended immediate speculation regarding his future by signing a new four and a half year contract on Merseyside in December.

But while Suarez has spear-headed Liverpool's quest to win their first league title in 24 years, his former international teammate Forlan believes a move to United would see him prosper further.

"We spoke a few days ago. He asked me if I think he should stay at Liverpool," Forlan told Brazilian paper Lance!, the Mirror report.

"All I told him was to think about going to Manchester United. I know he loves Liverpool, the fans and the city, but I think the best thing for his career would be to move to Old Trafford."

Forlan, who joined J League club Cerezo Osaka in January, spent three years at United before goal-laden spells with Villarreal and Atletico Madrid in La Liga.

He starred alongside Suarez in Uruguay's 2010 World Cup campaign where the Liverpool striker first attracted controversy when he blocked Stephen Appiah's goal bound shot on the line in a quarter final clash with Ghana. Suarez was subsequently sent off but Ghana missed the resulting penalty before Uruguay eventually progressed to the semi-finals at their expense.

Controversy followed the 26-year-old to the Premier League but Forlan has paid tribute to the other side of Suarez, insisting his countryman has always been a dedicated professional.

"We've been friends and neighbours a long time," Forlan continued. "Contrary to what many people think, Suarez is a polite person, someone who is always willing to learn. He wants to be the best at what he does. We're always in contact, through the good times and the bad."
