Manchester United boss Sir Alex Ferguson has hinted that next season may be his final year at Old Trafford.

The Manchester United manager was speaking at the unveiling of a statute in his honour outside Old Trafford, with some of the biggest names in the club's history in attendance.

And, according to the Daily Express, the United boss revealed that he could call it a day at the end of the 2013-14 season.

Ferguson, who will be 71 on December 31, said: "I've had 26 years at the club so far. And when the time comes and I decide to hang up my boots at - who knows - maybe 27 years, I think it will be a testimony to the work I've done at the club."

The Manchester United boss is the most successful manager in the club's history, and it's longest serving.

During his 26-year reign at Old Trafford, Manchester United have won 12 Premier League titles, five FA Cups, four League Cups, and two Champions Leagues.

Cristiano Ronaldo and David Beckham sent video messages congratulating their former-boss on his achievement.

Ferguson's Manchester United side take on Queens Park Rangers in the Premier League on Saturday, looking to secure the three points that will take them top of the Premier League table, at least until Manchester City play Chelsea on Sunday.

QPR are currently bottom of the table, with just four points from 12 matches, and sacked their manager Mark Hughes on Friday, replacing him with former-Tottenham manager Harry Redknapp.
