Swansea City are too reliant on Andre Ayew and Gylfi Sigurdsson for goals, according to coach Alan Curtis.
Swansea signed striker Alberto Paloschi in January, though the Italian has yet to score for his new club.
"We've lacked somebody since Wilfried [Bony] has gone," said Curtis, of the striker who departed in January 2015.

"We brought Alberto in to score goals but the responsibility has to lie with the team," said Curtis.
"Alberto wasn't brought in to be the main man but to make a contribution.
"I think we're too reliant on Andre and Gylfi to get our goals, and it needs to be spread out."
Swansea visit second-placed Tottenham on Sunday, taking on a team second in the Premier League scoring charts with 47 and who have conceded only 20, fewer than any other side in the division.
By contrast, the Swans hover just three points above the relegation zone in 16th place.
Spurs face Fiorentina in the second leg of their Europa League tie on Thursday and are just two points behind the Premier League's surprising leaders, Leicester, with 12 games left in the league season.
"I think they've [Tottenham] done exceptionally well," said Curtis.
"They've got a great opportunity to win the league this year and they're still in the Europa League.
"I don't see any reason why they can't [win the league]. They've shown this year they can go all the way."
