West Ham boss Alan Curbishley has hit out at the supporters who barracked Luis Boa Morte.
Boa Morte was booed by Hammers fans during their 1-0 win over Liverpool in midweek.
The Portuguese international admitted he was hurt by the jeers from his own supporters and Curbishley has called on all the fans to get behind his players.
"I was very disappointed with that and the rest of the players were," Curbishley told the club's official website.
"You don't like to hear that and let's hope it is a one-off.
"I would ask the fans to get behind the players because they can all surely see that everybody is committed at the moment here at the club. They are giving everything."
