Man Utd target Lewandowski wants to join Bayern Munich in 2014
According to Sport24, the 25-year-old is out of contract at the end of the season and has been repeatedly linked to a move to European champions Bayern.
The Poland striker is set to make an announcement about his future in January, when he is expected to confirm his move to Munich for next season, the report said.
With 11 goals in 16 league games this season, Lewandowski says he is frustrated by Dortmund's lack of Bundesliga form with Borussia third and 12 points behind leaders Bayern Munich in the table after three defeats in their last five games, the report added. (ANI)
