This is not easy, by any means.
Since the year 2000, there have been 244 full-time managerial positions in the Premier League on a full time basis. (Don't worry, we're not sadists. We haven't included caretakers who weren't eventually given the gig on a full time basis. We've also left out official interim managers, so very sorry to Gus Hiddink fans out there.)
But how many can you name?
We've given you the years they were there and the club they managed. Don't worry though, you don't have to name 244 managers. There are a huge amount of duplicates, triplicates, and even a septlicate (Ed.: not a word). Obviously, you only have to type in each manager once.
You've got 20 minutes for this one, so there's plenty of time. But we fear you will spend a good 5 minutes of it racking your brains for the last 20 or so you can't place.
We don't expect anyone to get full marks here. There are a number of guys who were around for a long time, and others who made a big, memorable impact in a relatively short time. A lot of Premier League managers were very forgettable though, and a number of clubs were quicker with the axe for full-time appointments than others were with caretakers.
Good luck and please let us know how you get on.
