He's a beast? Is that why Bayern want to sell?
Have you read Bayerns statements? They do NOT want to sell him, he said he wants to leave.
Reasons why Bayern would sell him? They have injury prone players in Thiago, Robben, Ribery, Javi, Boateng etc. etc. - it would make sense for the board to start reducing these numbers.
Another reason? Bayern has: Javi Martinez, Thiago, Vidal, Rudy, Goretzka, James, Tolisso and several youngsters for a few midfield positions.
Another reason? Bayern does not force players to stick around if they want to leave and Bayern has replacement
Heres Rummenigges statement: Rummenigge: „Davon ist mir nichts bekannt. Bei uns hat sich kein Klub gemeldet, und auch Thiago nicht. Wir planen weiter mit ihm. Wobei ich sagen muss, dass wir sehr viele Mittelfeldspieler im Kader haben. Für neun Mann haben wir je nach System nur drei bis vier Positionen zu vergeben. Der Kader, wie er jetzt dasteht, ist top. Wenn wir aber Spieler abgeben, schließe ich auch nicht aus, dass wir noch etwas machen.“
Translates to: I dont know anything about it, neither a club nor Thiago has contacted us about this, we still plan with him but i gotta say that we have 9 midfield players in the squad. We only have 3-4 positions for 9 guys. Our team is good as it is, but if we sell someone we might buy someone aswell.
So obviously Bayern will not try to keep the injury prone players out of these 9 (Vidal, Thiago) and instead build for the future with the likes of Goretzka.
