Hertha Berlin have dismissed reports suggesting they would be willing to let Pierre-Michel Lasogga leave the club on a permanent basis.
Hamburg have taken the highly-rated 21-year-old striker on a season-long loan deal and confirmed earlier this week they would then be interested in buying him next summer.
There had been speculation that Hertha would be ready to sell for £5.9million, but club spokesperson Peter Bohmbach has insisted there are no plans to let him go.
Bohmbach told Deutsche Presseagentur: "We have a strong and clear agreement.
"At this point in time Pierre-Michel Lasogga is on loan at Hamburg. He still has a contract left at our club and will be back in training with our club come the new campaign."
Lasogga, who joined Hertha from Bayer Leverkusen in 2010, has two years remaining on his current deal.
