You could think about Thomas Tuchel from Mainz05.
positives:
- plays nice offensive football
- works with lower budget than many other Bundesliga teams
- brings out young talents from one of the best youth academies on regular basis (Kirchhoff, Schürrle)
- outperforms expectations every year, it seems
- speaks perfect english (studied english after player-career)
negatives:
- contract runs another year (until summer of 2015)
- very thin-skinned like Klopp when it comes to doing interviews after losses or talking about controversial ref-decisions
- little international experience (i think it was one europe league participation)
- no international pedigree/respect, when it comes to working with a roster full of international superstars
It is said he may leave Mainz after 2015, when he coached the 1st team for 6 seasons and may go to another team like Leverkusen, Schalke or to the Premier League. Only other spots in Bundesliga where i can see him is Bayern, Dortmund, Wolfsburg, Gladbach, but they are happy with current coaching situations. Schalke is unhappy after every loss and Hyppiä may have a hard next season, when Sam is gone and Kießling won´t score like in first half of 13/14.
Maybe Tuchel would be someone for Arsenal (lower budget than biggest spenders, improve young talent, offensive-minded, exceed expectations)...?
