The 21-year-old spent last season on loan at Everton, scoring 15 Premier League goals, and said earlier this month he was not fazed by the impending arrival of Diego Costa because 'many clubs' are interested in his services.
Lukaku said: "I'm not thinking about myself at the moment. I'm only thinking about Belgium. We have waited 12 years to be at a World Cup and I am only thinking about representing the team in the best manner possible.
"If we all do well, then it will be a benefit to all of us [in terms of possible transfers], but at the moment I am not thinking about my future. Not until after the World Cup."
