Manchester United are lining up a swap bid for Borussia Dortmund striker Erling Haaland.
Mundo Deportivo says United are considering using Anthony Martial in a swap deal to beat Chelsea to the signing of Haaland.
United have been weighing up whether to use Martial as bait to land Haaland, who recently turned 21.
Chelsea are currently the club most eager to land the Norwegian but the Red Devils are also long-term admirers.
It is unclear whether Dortmund would be keen on taking Martial to the Bundesliga if United firmed up their interest with a formal bid.
