Speaking to Football League World, Palmer said: "Three go up from League Two, so signing an additional striker you would feel they have enough firepower to ensure they are promoted to League One and back-to-back promotions.
“Phil Parkinson will have his hands full in keeping the quality of strikers he has on the books all happy. But I’m sure Phil and the hierarchy without taking their eye off the ball are planning for life in League One and the signing of Jack Marriott proves that, with his quality at League One level."
