100 wins from 181 games.

Not bad, but he should be demanding of himself in his way to achieve first-class honours.
55% is staggeringly good, isn't it, considering the team and position he inherited? Klopp's reign at Liverpool is generally considered a success, included a league title, three domestic cups and a Champions League, and his win percentage was only 62%. Which is like, one more win than Unai every 15 games.
I hope to God we can keep him long enough to break the back of building a commercial operation commensurate with regular European football, and then give him the tools and financial muscle needed to back him properly.
