No player should..in all honesty react to fans giving them grief. Yes he has been getting it tight this season..and frankly rightly so..because he as been so shite compared to last season where he was almost talismatic (is that even a word..haha)
The example I would look at is Steve Kean down at Blackburn. He has had the worst ive ever seen with regards to chanting..protests outside the ground and everything. The recent Bolton game at Ewood was shocking..and yet does he run to the crowd and give them abuse back? Does he hell. Professional. That's what walker should be as well.
Yes the team needs vocal backing..but teams that have much smaller supports seem to get by..so why can't the players of Raith?
