The former Manchester United youngster has arguably been the Hammers most impressive player so far this season, but his attitude is still being questioned by many.
Morrison hit out at Crystal Palace defender Joel Ward after the final whistle at Selhurst Park on Tuesday and was shown a yellow card, his fifth of the season meaning he will miss today’s trip to Liverpool.
Earlier in the season, Morrison was involved in an altercation with Wilfried Zaha during an England under-21 game, although no action has been taken over that.
Allardyce seems to have tamed the 20 year old since the summer and the boss knows Morrison will not react like that again.
“He has gone through the normal procedure after showing dissent in a game,” Allardyce said.
“That is dealt with by a laid-out regulation at the club, as well as the on-field discipline scenario.
“For Ravel, he is a young man who loses his cool at times, as many young talented players have done over the years, so he knows not to do that thing again.”
