In his regular email to supporters, McCall said: "I understand there were some disgruntled voices and I don't mind that coming to myself in terms of team selections, substitutions, whether I've got ginger hair or wearing shorts, it doesn't matter.
"I've been in football now for 40 years, watching, playing, scouting and managing, and I have never, ever - not even once - seen any situation where a crowd are getting on top of a player and it doing him any good.
"I didn't enjoy hearing it when I stood on the terraces at Elland Road as a kid, I hated it when one of my team-mates was getting abuse when I played the game, and certainly don't enjoy it when I am a manager and one of my players is getting it to the point where it is putting him off his game.
"If you use your common sense, and I know it is frustrating, there is no logical way that any individual will respond positively to personal abuse.
"I am not stupid, I know it goes on at every club but I want us here at Motherwell to rise above it.
"This is our team, we all want to win a game of football and the very best way is to get behind the lads and support them when things aren't going well."
