Fellaini struck for Belgium in their World Cup win over Algeria yesterday.
Vertonghen said: "With Belgium, we know how to use him and I don't know whether they do in his other team.
"Marouane always is very important for the Belgian team. I know there has been a lot of pressure on him from the fans in England but in Belgium he always does well and scores goals.
"I'm very pleased for him and I gave him a little hug after the game because I know that goal meant a lot to him."
