Cole admitted the relationship between players and fans has changed since he made his professional debut 15 years ago.
He told the Green Soccer Journal magazine: “I’d say it’s changed from when I first started out as a player but what can you do?
“There are more opinions in football today.
“More people have strong opinions and they’ll tell you what they think of you without actually realising what you’ve achieved and how good you are.
“I know that if I walked into someone’s house or their office and I watched them at work I’d probably say ‘You’re not doing that right’ too.
“I might not really know what it is that they’re doing but I’m watching them do it so...
“As players we understand it. Of course, fans pay their money to come, of course they’ve got a right to air their feelings, to say what they feel or say what they see, basically.”
