The Frenchman is currently on a season-long loan deal at The Hawthorns and has scored twice in three Premier League appearances.
But QPR midfielder Barton, who played with Amalfitano during his season-long loan at Marseille in 2012-13, was keen for his boss Harry Redknapp to recruit the 28-year-old.
However, the former Newcastle United man claims there is a lack of knowledge in England when it comes to talent in Ligue 1.
"I am still in contact with some of my former team-mates. I speak to Morgan. I really tried to get him here," he told l'Equipe.
"I spoke about him to the manager, to scouts, but here we don't know the French championship.
"I said to them: 'He is a good player - get him over here'. They told me: 'We don't even know who he is.'"
Amalfitano scored the first goal in West Brom's 2-1 win over Manchester United at Old Trafford on Saturday as Steve Clarke's men moved to 10th in the table.
"When he scored this weekend against Manchester United, I took the mickey out of them (QPR)," he added.
"I knew that in England, he would do well."
