Borussia Dortmund are prioritising finishing the top-four in the Bundesliga in order to keep Erling Haaland, according to sporting director Michael Zorc.
The Norwegian striker has constantly said he wants to be playing in the Champions League this season, with Dortmund currently sitting fifth on the table.
Manchester City, Real Madrid, Manchester United and Chelsea have all been linked with the 22-year-old.
"I have never seen someone like him. We can search Europe-wide," the Dortmund sporting director told Welt am Sonntag.
"If he ever left us somewhere, there would only be a handful of clubs, but we'll try to keep him as long as possible for sporting reasons."
Dortmund are into the Champions League quarter-finals thanks to Haaland's incredible performance over two legs against Sevilla.
But Zorc says they must focus on ensuring they play in the competition next season by prioritising their domestic form.
On the club's Champions League run, Zorc added: "We don't want to play in the Europa League on Thursdays.
"We want to give our calling card in the Champions League."
