With Frank de Boer announced as Crystal Palace boss on Tuesday, it now means there are 20 Premier League Managers in place.

However, how long has each of them held down the job at their current club.

No marks for guessing that de Boer is the new boy and Arsene Wenger (20 years 269 days) longest serving, after having successfully staved off the latest revolt by Arsenal fans after their team only won one trophy (third FA Cup in last four years) and finished fifth in the league.

Interesting to see that the two who come next after Wenger, are both young English managers who have been at their clubs for over four years.

Both Sean Dyche and Eddie Howe have done excellent jobs at their clubs and interesting to see whether ‘bigger’ clubs will take a chance of one or both of them if they continue to progress.

Despite only being appointed a year past March, Rafa Benitez is actually the 11th longest serving of the current 20 bosses, having been at Newcastle for 1 year and 108 days so far.

It would be nice to think we will have longevity with Rafa and he will prove to be the longest serving on this list one day…

Maybe interesting to note as well, that whilst the fashion is increasingly for Premier League Managers to be brought in from abroad, five of the seven longest serving were born in the UK.
