Dortmund supposedly looking at Favre.
I'm not sure what Tuchel's done to lose favour there (some say transfer disagreements, some say Tuchel is difficult/detached on a personal level) but I'm still a fan. There's no way Moshiri/Kenwright would entertain the idea but I'd ditch Koeman for Tuchel in a heartbeat. I'd do the same for Favre, mind you (that ship has sailed unfortunately).
It would be a perfect time for Arsenal to let Wenger go. Even if rumours of Tuchel being difficult are true, he's an outstanding tactician and he'd breathe new life into an already excellent squad.
