Manchester United striker Ole Gunnar Solskjaer is set to announce his retirement from football on Tuesday.
The 34-year-old Norwegian has been plagued by a series of knee injuries.

Solskjaer, who scored the winner in the Champions League final against Bayern Munich in 1999, made several comebacks in the past four years.

Solskjaer joined United from Molde for £1.5m in 1996 and has the former Norway international has made 366 appearances for United, scoring 126 goals.

The striker scored 11 goals as the Red Devils reclaimed their Premier League crown last season.

Solskjaer's last game for Sir Alex Ferguson's side was the FA Cup final defeat to Chelsea on 19 May 19 when he came on as an extra-time substitute at Wembley.

He has already spent time at United coaching young players and was appointed a club ambassador last year.

The retirement of Solskjaer leaves Ferguson with only three strikers - Wayne Rooney, Louis Saha and Carlos Tevez - the latter being the only one presently fully fit.

Ferguson has been linked with a move for Bolton's Nicolas Anelka and Spurs striker Dimitar Berbatov, although the latter has insisted his immediate future lies at White Hart Lane.

United have sold fellow strikers Alan Smith to Newcastle and Giuseppe Rossi to Villarreal.

Tevez has also been included in Argentina's squad for the friendly against Australia in Melbourne next month, which could further stretch Ferguson's resources.

Saha, whose own United career has been dogged by injury, had hoped to make his return against Spurs at the weekend but his comeback was aborted.

He is expected to be fit to face Sunderland at the weekend, but his persistent knee problems have proved a major cause of concern.

Solskjaer returned to fitness last term, and was hopeful of playing a meaningful role this season, despite undergoing minor knee surgery in June.

But he has had problems during his rehabilitation and recently admitted he fully expected this to be his last season.

Now the announcement that one of Old Trafford's most popular figures is quitting the game has been brought forward.
