Who is Favre?
Defo the best option if you ask me.
Last three jobs on his CV (oldest to newest):
Won the Swiss league with an average squad age of 21.5.
Took over 10th placed Hertha BSC and led them to 4th.
Totally revived the German 'sleeping giant' of Monchengladbach - took them over when they were in relegation playoffs. Guided them to 3rd and they're now firmly ensconced in the German elite again even though they're poor as balls.
Plays his own flexible version of a 4-4-2. Very defensively organised, extremely fast short-passing counterattacks.
Great track record with youth (in Germany too, not just in Switzerland).
Passionate and massive attention to detail.
Is free.
Only black mark for me is he resigned from Moncengladbach (after such huge success with them for 4.5 years) after losing the first 5 games of this season. The club actually wanted to keep him on but he felt like he'd come to the end of what he can do there (which, considering how good Mourinho is and what happened at Chelsea this season, I think is actually kinda to be expected with almost any manager at any club after a significant amount of time). He left the club in a good state though and they're 5th right now.
