Jurgen Klopp has told Manchester United that Robert Lewandowski is not for sale.

Sir Alex Ferguson has lost Michael Owen already this summer, and he also looks certain to lose another attacking option when Dimitar Berbatov, as expected, leaves.

The United boss has been linked with Poland international Lewandowski, 23, but Borussia Dortmund coach Klopp insists his 22-goal striker is not for sale.

"We will not sell Robert Lewandowski, not for any price," he told Suddeutsche Zeitung. "Our biggest obligation is to have a strong squad. He will remain at our club."
