The Belgium international's agent Christoph Henrotay is adamant that the former Anderlecht man still has ambitions of making a success of his time at the European champions.
Asked if the youngster still has a long-term future at Stamford Bridge, Henrotay told The Newspaper in Belgium: "Of course, Chelsea count on Lukaku.
"They will continue to follow him and evaluate after the season. There was so much interest. But West Brom is an ideal club at which to evolve.
"It is also important that Romelu can keep playing in the Premier League. Romelu has thanked Chelsea.
"The boy has two seasons of football played with Anderlecht. Another year on the bench was not an option. This is the best for all parties."
