4. Julian Nagelsmann
At just 30 years old, Nagelsmann is widely tipped as one of the great future managers, so Arsenal may want to hire him as a future long term guy to handle the team.
Hoffenheim boss is younger than some of the senior players like Koscielny and Cech which may create some problems for Arsenal but Nagelsmann’s excellent start with Hoffenheim is something to look at. They finished fourth in the Bundesliga and qualified for the UCL play-offs.
