Borussia Dortmund are showing serious interest in Ajax striker Sebastien Haller.

The attacker, who flopped at West Ham United in the Premier League, is a hot property after his impressive form under Erik ten Hag.

Haller has 33 goals in 39 games for the Dutch champions this term, as they look to win another Eredivisie.

Ivory Coast international Haller was linked to Manchester United by The Sun, where ten Hag is set to take over as manager.

The source goes on to suggest that Dortmund view Haller as an option if they sell Erling Haaland to Manchester City or Real Madrid.

Haller has two years remaining on his contract at Ajax, and has not indicated a desire to leave.
