£50m according to the back of one of the rags I've seen. No way is he worth that much! Linked to Arsenal but he has been for the last few years.
Of course he is worth that much. If you compare him to Mane at £36million and Wijnaldum at £25million then he definitely is. He's pretty much first choice for Germany now and is playing regularly Champions League football. Also Wolfsburg paid £25.5million for him a year ago so they are going to want more than that now!
