The Blues have sent the 20-year old Belgium international to Everton for a season-long loan, following his impressive spell at West Bromwich Albion last term, so he can develop quickly in a first team environment.
However, Emenalo insists the Southwest Londoners will not place too much pressure on Lukaku, especially seeing as they have plenty of attacking options following the summer arrival of Samuel Eto'o from Anzhi Makhachkala.
"But we are not desperate and we know for the future we have Romelu Lukaku and incredible hope that he will come through and lead the line.
"People keep forgetting that he is only 20, and looking at the short-term plan, we don't want to put too much pressure on a young player like him.
"So if we weren't able to get Rooney and we had Lukaku, (Demba) Ba and (Fernando) Torres, we felt comfortable with them but we also felt comfortable to bring Eto'o to give us a little bit of competition, because we wanted to freshen up that position."
