Crystal Palace co-chairman Steve Parish admits they need to strengthen their attacking options.
Dwight Gayle has arrived from Peterborough United this summer, while free agents Stephen Dobbie and Jerome Thomas have also signed.
"People have got to think we lost Wilfried Zaha and then Glenn Murray to injury, and we didn't concede a goal in the three play-off games," Parish told the Croydon Advertiser.
"We've obviously lost in an attacking sense and we weren't bad defensively anyway.
"I think it's about getting your priorities first at the top end of the pitch because of being a bit thin there."
