Borussia Dortmund are chasing Aston Villa striker Christian Benteke, according to the player's agent.
The 22-year-old, who arrived in the Premier League from Genk in a €8 million move last summer, has notched 23 goals in his debut season in England including a strike in Saturday's 2-1 loss to Chelsea at Villa Park.
Dortmund's chief transfer negotiator Michael Zorc was in attendance at the weekend, with the Champions League finalists thought to be scouting potential replacements from Robert Lewandowski, who is expected to link up with Mario Gotze at Bayern Munich.
"I am aware of the Dortmund representation at Villa Park for the Chelsea match, but Christian is still a Villa player and nothing has changed on that point," Eris Kismet told ESPN.
"There were a lot of scouts from many teams who have an interest in Christian. Now Aston Villa's future in the Premier League is decided we will know more.
"It is natural for many teams to show an interest when Christian has had such a good season and scored many goals, but it is his first season in the Premier League."
Benteke will not play for Villa again this season after being sent off against Chelsea and Lambert has hinted at a new deal for the Belgium international after his fine form this term.
