It does mean that the longest serving Premiership manager next season will be Eddie Howe.
Blimey! That's actually a far more interesting fact than Wenger stepping down.
I looked up the list of longest-serving managers and five of the next seven after Wenger are recently promoted clubs - Howe at Bournemouth, Dyche at Burnley, Hughton at Brighton, Wagner at Huddersfield and Benitez at Newcastle.
I guess this shows that you can be allowed the luxury of a few seasons if you win a promotion and/or a cup, but once you start to stagnate into a bog-standard mid-table club (Everton, West Ham, Stoke), the revolving door policy kicks in.
The two interlopers in that bunch are Pochettino at Spurs and Klopp at Liverpool, but they are arguably the only two of the "Big Six" clubs that have showed real progress and improvement in the last few years. Man United, Chelsea and Arsenal have either remained static or gone backwards. City have only achieved the minimum expected given the manager and players at their disposal and Guardiola will be feeling the pressure to perform better in Europe next season.
It's a results business, Brian.
