Borussia Dortmund have made a €28 million bid for former West Ham striker Sebastien Haller according to a report.
Dutch outlet VI report that the Bundesliga runners-up have made their first offer for the Ivory Coast international and are looking for a quick resolution to the potential deal.
Dortmund have been linked with Haller for some time and appear to be flexing their muscle with a substantial opening bid.
Haller's contract at Ajax runs until 2025 and Ajax will be hoping they can hold onto their prized asset who was the third top scorer in last season's Champions League with 11 goals - only Robert Lewandowski and Karim Benzema scored more.
