Bayern Munich had reached an agreement over personal terms with Germany international Timo Werner before he signed a contract extension with RB Leipzig on Sunday.
The 23-year-old was expected to leave on a free transfer next summer after running down his contract in Saxony, but Werner's new deal sees him tied to the Red Bull Arena until 2023, or at least until his a release clause of around €30m is activated.
Werner's contract extension came out of the blue, and Sky.de claim that is in part due to the fact that he already had an agreement in place which would see him move to Bayern Munich either this summer or next.
