Liverpool “need another world-class striker”, says Harry Kewell, with Jurgen Klopp being urged to continue an elaborate summer recruitment drive.
The Reds have already invested heavily during the current window, with midfield duo Naby Keita and Fabinho brought on board.
Alisson has also joined in a £65 million ($85m) deal, making the Brazilian the most expensive goalkeeper in history.
Liverpool are considered to be building towards a bright future, with the likes of Mohamed Salah and Virgil van Dijk also drafted in over the last 12 months, but Kewell feels a proven frontman is still required in order to challenge for the Premier League title.
