Speaking to talkSPORT, veteran English head coach Neil Warnock said: "Since the Premier League started if I was picking my top five managers, I would pick Arsene Wenger as the number one. Only because he changed the whole outlook on modern footballers.
"Pep Guardiola would be second. I saw his teams first-hand last year and I've never seen a team with that kind of movement. His influence on the parks and the lower down leagues has been fantastic.
"I would put Jurgen Klopp third because I think he's just beginning and he will get even better. His outlook and everything he has done at the club and the future with the kids — I think he has got another 10 years coming forward. So I think he's third at the minute, but could easily be number one in a couple of years.
"Fourth, I would probably go with Sir Alex Ferguson. I just think he was in an era where it was all about man-management — it wasn't down to all the backroom staff — and Sir Alex was probably the best at that."
"Jose Mourinho is close. What I like about him is the way he deals with the media at the most difficult times, but I would still put him number five."
Neil Warnock's top 5 Premier League managers:
1. Arsene Wenger
2. Pep Guardiola
3. Jurgen Klopp
4. Sir Alex Ferguson
5. Jose Mourinho
The relationship between Warnock and Sir Alex broke down 15 years ago, when Man United's weakened side lost at home to West Ham on the final day of the 2005/06 season, a result which meant that the Englishman's Sheffield United side were relegated to the Championship.
