Positive thing is the knowledge and intelligence of Everton fans. Random Twitter or NSNO poster seems to know his football better than one of the best Premier league managers.
how do you equate Koeman as one of the best Premier league managers?
do you mean in the Premier league right now? or in the history of the Premier league? or during a set time period?
again, how have you come to that conclusion? What has he won? whats his win loss %?
