Think they were only at Leipzig together for about 6 months, Hasenhutl left at the end of the season.
If we were looking to replicate Leipzig's success then the bloke to go for is Ralph Rangnick who oversees football operations for the Red Bull group of clubs. Has been linked with jobs in England, including the national team at one point. Now managing the Leipzig team as a temporary measure. No chance of getting him. If we did we could have 3 Ralphs at the club, Krueger, Rangnick, and Hassenhutl.
Perhaps that's where we're going wrong, jusy not enough Ralphs at the moment.
