Bayern Munich
There have been strong rumours in this regard, and Bayern currently is four points behind leaders Borussia Dortmund, even with a bulk of the season to go.
However, should the Bayern leadership seek a change, then Wenger could feature heavily.
Bayern sought him out before, with some offers made to him in the mid-2000s. Moreover, he speaks fluent German, has often said how he respects the Bundesliga and the German football system overall.
Bayern could do worse in this regard, and Wenger's attacking style would suit the quality of players they have on offer.
Could he win a Champions League with the club? Who knows? It's what Bayern is looking for ultimately, like all big European clubs. However, with the players at his potential disposal, he can look to turn them into strong contenders. He is also used to competitive title fights, which looks like the resulting occurrence in Germany this year, with a resurgent Dortmund.
