The former Die Roten midfielder also says the club should “do everything” to try and lure Arsenal's Alexis Sanchez to the Allianz Arena
Former Bayern Munich midfielder Andreas Herzog has urged the Bundesliga champions to make a move for Borussia Dortmund star Ousmane Dembele.
The France international joined Dortmund from Rennes ahead of the 2016-17 campaign and has since developed into a key figure at Signal Iduna Park.
Dembele has had a hand in 17 Bundesliga goals this term, scoring six and creating 11 more, and he recently netted the winner in the 3-2 DFB-Pokal semi-final win over Bayern.
