Part Time Stuttgart Fan
I did not know Wenger approached Sven though, the media always spun it like he was an unwelcome interference from the dictatorship Wenger was running.
Reading Wenger's book though, he always liked to bring "the best of class" to the club for their expertise and looking at Sven's career trajectory at the time it makes sense.
Also speaks for Wenger. I always maintained one of his biggest mistakes was not bringing fresh backroom and coaching staff once in a while like e.g. Ferguson did every now and then to support him with the challenges of modern football, divide some responsibility and infuse fresh ideas on the pitch. E.g. I haven't really thought it out in any coherent manner, but I think it's really no coincidence Wenger and his free flowing, expressive football got into trouble with the arrival of highly organized spacial defending and gegenpressing, minimizing space and time you got on the ball thus making it harder to play as expressive and defined by individual choice as Wenger wanted to. Also you do need a certain standard of quality player for such football and the increased transfer fees for such players did the rest. It's actually baffling Wenger kept pulling out relative bargains and made them work for such a long time before the market soured completely and every guy with two feet suddenly cost 20m. A fresh assistant versed in such tactics could've worked wonders during Wenger's later years imo.
Coming back to my first thought - if Wenger approached Mislintat to revamp and strengthen his transfer department that actually speaks against my initial thought of Wenger not trying to change it up with backroom staff.
