Albion manager Mark McGhee today revealed his deep disappointment at the way players like Michel Kuipers have reacted to being left out of the side.
McGhee says they have a duty to support their team-mates, even if they feel hard done by.
Goalkeeper Kuipers was axed from the squad for last Saturday's game at Coventry following an angry reaction to being replaced by Wayne Henderson for the home match against Burnley four days earlier.
It was the latest in a series of outbursts by players over team selection.
Leon Knight, now at Swansea, stormed out of Withdean when McGhee left him out against Hull before Christmas.
Flo Chaigneau followed suit when Kuipers was preferred against QPR on Boxing Day, then Kuipers had heated discussions with McGhee and coach Dean White as Chaigneau took over for the trip to Southampton on January 2.
Meanwhile, out-of-favour forward Mark McCammon aired grievances on the BBC Southern Counties Radio phone-in after the Burnley match.
"It disappoints me massively," McGhee said. "Apart from anything else they have got a responsibility to their team-mates, regardless about how they feel about me.
"At the end of the day I have got to make these decisions and if they fall out with me because of that they still have a duty to their team-mates to support them.
"Michel doesn't seem to be able to accept that we are making the decisions on the goalkeeper based on performance.
"Michel played really well in the Reserves to the point where I had no option but to put him in against Leeds.
"He did really well against Leeds. I thought he had a poor second half against Sheffield United and, on the strength of that, I decided to play Wayne, nothing else.
"I think that was proven right in terms of Wayne's distribution against Burnley, which gave us the opportunity to win the game although we didn't go on to win it.
"Wayne kept his place and his performance on Saturday justified that again. I thought he was terrific, even though in the second half more was asked of him at a time when he was struggling a bit with his hip.
"Michel hasn't accepted that and therefore isn't in the right frame of mind to be sitting ready to come off the bench."
McGhee insists morale in the camp remains high and has invited doubting fans to see it for themselves.
"We have a fantastic spirit, a wonderful spirit, and anyone suggesting otherwise can come up to training and witness it for themselves," he added. "There is an open invitation."
