They used to say the role of England manager was the impossible job, but these days it feels like the Old Trafford hot seat is the one that must come with a health warning. In fact, it's become so impossible that just being linked with it is enough to take a hammer to a promising career.
When Leicester City thrashed Manchester United back in September it felt like Brendan Rodgers was well-positioned to replace Ole Gunnar Solskjaer, but since then the Foxes have had such a poor season that the Northern Irishman isn't even part of the discussion now that a permanent manager is being sought.
That battle has been waged between Mauricio Pochettino and Erik ten Hag, but if the detriment to Rodgers was immediate, the fall from grace for the Paris Saint-Germain boss has only recently arrived and even Ten Hag is starting to have a wobble.
