Great idea for a quiz. Needs updating though. You also need to at least treble the time. There are over 200 different answers.
Also, you need to look at the type ins for a few, Leicester manager in 15-17 requires full name, but his surname is accepted elsewhere. Similar issue with Boro manager 00-01.
Howard Wilkinson is listed as managing from 1998-1996. Graham is '96-'98. That's most definitely not correct. Unless Wilkinson's a time traveller. So... probably fix that?
Ha actually there isn’t. Heckingbottom took over on an interim basis at the end of the 2020/21 season, then Jokanovic got appointed, but got sacked a few months into the 2021/22 season. Heckingbottom was then appointed permanently and has been in charge ever since. So the fact he appears twice denotes two separate spells in charge.
It's always nice coming back to this quiz every year or so, but it still needs more time. Let people enjoy themselves and rack their brains over individual clubs and dates, rather than rush as many answers they can think of off the top of their head.
