The Norwegian forward, who scored the winner in the Champions League final against Bayern Munich as United won the Treble in 1999, made several comebacks in the last four years but has failed to fully overcome the problem.

And according to The Sun, the 34-year-old - who has not appeared in any of United's matches so far this season - will finally admit defeat in his long-running battle with injury and call it a day.

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

He has already spent time at United coaching young players as he looks forward to life after his playing career.
