Er… what does that mean, exactly?
I note in passing that a train leaves the station, gets to its terminus. And it comes back again.
By the way, I should specify that I'm never normally favourable to bringing players back who've left. Even the great Shaun W-P, it didn't really work second time around, did it? But you've got to consider circumstances, and take every case on its merit.
Anyway, this is all hypothetical. He hasn't said he wants to leave Bayern, as far as I know, and we haven't said we want him.
It is, to use a choice word, a nugatory discussion. Not to say otiose.
