West Ham captain Nigel Reo-Coker has received hate mail during the club's recent run of bad form.
Reo-Coker scored the only goal in West Ham's win over Man Utd
Some fans blamed him for the sacking of boss Alan Pardew and hate mail was sent to the club before he scored Sunday's winner against Manchester United.
"It got to a boiling point for a young man," his agent Tony Finnigan told BBC Five Live Sport.
"I told him to stick it in the dustbin and get ready to go to war against one of the best teams in Europe."
Midfielder Reo-Coker's goal at the weekend ensured that new boss Alan Curbishley celebrated his first match in charge with a 1-0 victory over the Premiership leaders.
But the 22-year-old reportedly remains the target of a number of top clubs and plans talks with Curbishley over his future.
"He is under contract and he is happy at West Ham but I don't know how long he wants to play in front of boos," added Finnigan.
"We will be sitting down with the manager to talk about him in a clear-the-air meeting.
"If you got approached by one of the top sides in Europe then of course you would be flattered but I don't want to talk about something that is hypothetical."
