Don't like to hear booing although it is totally understandable,I prefer to tut and frown.
unfortunately with this The players won't know anything is wrong, Klopp won't either and more importantly Big John from Boston will think everything is fine and dandy in the Liverpool garden.
Maybe a strong letter of disapproval might do the trick to certain players who have had a bad game.
Dear Emre Can,
Think you were absolutely rubbish today and anymore repeats of this type of behaviour and performance and I will be forced to remove my future support for you.
Yours Sincerely
An Unhappy Fan....
