The Toffees’ poor run of form in the Premier League continued, as they went down 3-2 to Watford at Vicarage Road.
Koeman has taken to Twitter to express his frustration at the final result, with Everton fans responding to his message on the social networking site.
@John_B58 That is the thing for me John. I'm a fan of him but 1 in 10 doesn't lie. We can't keep trying the same thing every week— Tony Fitzpatrick (@toefitz) December 10, 2016
@RonaldKoeman 4-4-2 give lukaku a help and stop playing it to his feet let him run into through balls that's his forte— Stew EFC (@swa56ply) December 10, 2016
@RonaldKoeman playing dross like McCarthy and Mirallas didn't help.. Are you blind to how well our youth team are playing?— Grandmaster Tash™ (@danielvane) December 10, 2016
@RonaldKoeman It's true that a manager can only be judged on his results, so one win in ten speaks volumes. Patience is now finished.— DAW (@DavyEFC) December 10, 2016
