Bolton Wanderers boss Gary Megson admits he was disappointed with Ivan Campo's reaction to being substituted during yesterday's 0-0 draw with Manchester City.
Megson said: "I have spoken to Ivan a couple of times and all the players about it. Ivan has done that a couple of times and I don't expect anybody to be happy when they come off but what I do expect is that we all stick together.
"You don't want people pleased when they are brought off the field, I was never happy about it myself when I was a player.
"But you make your decision and think it is the right thing to do, therefore done in the best interest of the club."
