I don't necessarily think Frank is the absolute best option out there we could get, but what the fuck is that list? Jaissle is in Saudi, his most recent job after being sacked on the eve of the new season by RB Salzburg, Todesco was so shit at Belgium Courtois literally refused to play for him, Hoeness just took Stuttgart to 9th in Bundesliga (essentially the same as Frank's 10th with Brentford since BL is an 18 team league, except they have the 7th largest wage bill in Bundesliga to Frank's 17th in PL) and Mckenna has just been relegated on 22 points. Xavi and Inzaghi granted, good names.
You bang on about Frank having no European experience but want to sign a manager in Todesco who, as RB Leipzig manager, managed to get knocked out of the Europa league by Rangers and lost 4-1 at home to a Shakhtar Donetsk side decimated by the exodus of non-Ukrainian internationals after the start of the war with Russia and stripped of their most promising player in Mudryk. Or one in Hoeness who finished 26th in the CL league stage. Hardly inspired.
