Swansea defender Mike van der Hoorn renews battle with Zlatan Ibrahimovic admitting the Manchester United striker has left him bemused in the past.
Ibrahimovic's form in front of goal mirrors that of a stuttering United side who have failed to score in their last three Premier League games.
The veteran Swede has scored only once in 11 games and has not found the net in the league for nearly two months ahead of United's visit to Swansea on Sunday.
But former Ajax centre-back Van der Hoorn has painful memories of marking Ibrahimovic in a Champions League tie against Paris St Germain in November 2014.
