Real Madrid have been tracking Timo Werner for some time but a strange situation could prevent him from joining the club.

The European champions have been scouting him all season as they search for a new centre-forward, with Karim Benzema's time at the club approaching its end.

Werner, still only 21, has 12 goals in 20 appearances so far this season and netted 26 for club and country last season.

In many ways, he seems the perfect fit for Real, but there is one strange physical problem that could hold him back.
