Manchester United manager David Moyes is reportedly weighing up a move for Bayern Munich striker Mario Mandzukic.
The 27-year-old, who has scored 12 goals in 21 appearances this season, is said to be unsettled by the pending arrival of Robert Lewandowski from Borussia Dortmund.
According to the Daily Mail, the United boss has travelled to Germany with coach Phil Neville to watch Mandzukic when Bayern face Borussia Monchengladbach in the Bundesliga on Friday evening.
Moyes is believed to be a long-term admirer of the Croatian international, having sent scouts to watch him during his time as manager of Everton.
Mandzukic joined Bayern from Wolfsburg in the summer of 2012.
