HOW MANY MANAGERS DID CHELSEA HAVE WHILE ARSENE WENGER WAS AT ARSENAL.?

This question might interest many football fans . 1) Arsene Wenger joined Arsenal in the year 1996. And is still there almost twenty years a long time. But now Chelsea had at that very same time roughly twenty long years a total of 16, sixteen managers at Chelsea . Now I am counting it as 16, sixteen with the two terms of Jose Mourinho and another two terms of Guus Hiddink as interim manager . Not at all nice for the stability of a club.
