Bayern Munich have an informal agreement with Serge Gnabry's advisers, it has been revealed.

BILD says while there is nothing formal with the new Werder Bremen signing, Bayern have reached agreement with his agents.

Gnabry joined Werder last week from Arsenal amid talk of a deal also with Bayern.

However, it's now been revealed Bayern have been assured by Gnabry's minders they'll be alerted should any major offer arrive between now and the end of his Werder deal in 2020.

For their part, Bayern have made it clear to Gnabry that he is a long-term target and will be watched regularly this season.
