Newcastle United are intensifying their search for a new number nine this summer, with Chelsea strikers Nicolas Jackson and Liam Delap emerging as primary targets. The Magpies have struggled to fill the void left by Alexander Isak, who moved to Liverpool last September for £125 million ($166m), as neither Yoane Wissa nor Nick Woltemade have fully convinced as a leading option. Recent tactical decisions to deploy Will Osula and Anthony Gordon centrally against Barcelona, despite Wissa and Woltemade being available, highlighted the need for a new focal point. Woltemade, who joined from Stuttgart in August 2025 for £65 million ($87m), has 11 goals in 44 games. Meanwhile, Wissa arrived from Brentford last summer for £50 million ($66m) but, after an early knee injury, has managed only three goals in 21 appearances.Newcastle are actively working on recruiting a new striker and have focused on the Chelsea pair. While they are not looking to sign both, Jackson and Delap are viewed as high-quality alternatives. Jackson, who joined Bayern Munich on loan from Chelsea last summer, has registered a steady return with seven goals in 26 appearances. Meanwhile, Delap’s numbers have been more modest, scoring twice in 31 games since moving to Chelsea from Ipswich Town last summer. Neither player is currently guaranteed a long-term future at Stamford Bridge, making them viable options for a move to Tyneside.Despite his modest scoring record, the Senegal international is still highly regarded in Bavaria, and there remains a possibility of a renewed approach that would see him return to Germany in a secondary role to Harry Kane. However, TEAMtalk sources indicate Jackson is prioritising regular first-team football, something Newcastle are in a strong position to offer.Add GOAL.com as a preferred source on Google to see more of our reportingRegarding Delap, Newcastle explored a move for him last summer and remain convinced of his "significant upside." If Chelsea succeed in bringing in further attacking reinforcements, Delap is expected to be made available for transfer, and Newcastle’s interest has not waned.
