I'm always interested to see how new managers do in the Premier League and the impending arrival of Ralf Rangnick is intriguing to say the least.
When intelligent football people of the calibre of Jurgen Klopp, Thomas Tuchel and Ralph Hasenhuttl sing his praises, he clearly deserves respect.
Rangnick has no Premier League experience but neither did Arsene Wenger nor Klopp and they did more than all right. But there have to be big question marks as well.
Rangnick has had success at Schalke, Salzburg and Leipzig but has never been at a club with the levels of expectation and scrutiny you get at United.
