At risk of a Ole Vs Naglesmann battle, which I don't want to get into...Ole has achieved a lot more then Naglesmann, to say otherwise is massively incorrect.
Ole doesn't play the mind games or the press maybe as well as he should, but his use of language and impact of words used in his press conferences/interviews should not be overlooked. He is a positive manager who uses language to great effect, something which he has obviously worked on before he took the United job.
Naglesmann is having a good season no doubt, but a trophy is a must for him as it is for Ole. Otherwise a good season is just that, good, but not great. And for a club in RB that are now consistently one of the top spenders in the Bundesliga I'd imagine that won't be good enough for too much longer.
