I don't get why Bayern wanted Gnabry. He will never be good enough for them.Dortmund actually do it more than your lot but that's a different story for a different day.
Bayern however have the extremely uncanny ability to snag a player or two from teams who look like being able to eventually challenge them. Lewa, Goetze, Gomez, Sule, Rudy, Goretzka?, Gnabry, Hummels, Klose, Neuer, Wagner, Mandzukic.
Fair list I'd say.
