Newcastle United are expected to invest heavily in their squad this summer.
Newcastle are currently the favourites to win promotion from the Championship next season, but there is a realisation that they will need to add to their squad to meet expectations.
Benitez is likely to be backed with funds, as he looks to assemble a squad capable of achieving promotion from the second tier.
Newcastle have already been linked with a host of targets, and Dyer believes the addition of a striker will be most crucial.
“They need a goalscorer – someone to get that 20 goals,” the former England international said. “They will identify someone and blow out any other club with regards to wages.”
Newcastle currently have the likes of Ayoze Perez, Aleksandar Mitrovic and Papiss Cisse competing for places up-front.
The trio have all shown flashes of quality, even at the top level, but they have no experience of playing in the Championship.
Adam Armstrong and Ivan Toney, two of Newcastle’s most promising youngsters, could also push for first-team places - but they are inexperienced.
Benitez appears to have made signing a striker one of his priorities this summer, with Ross McCormack and Dwight Gayle amongst the names linked.
