The Borussia Dortmund chief executive is hopeful the striker will see out his contract at Signal Iduna Park, while stressing that no more players will be offered release clauses
Lewandowski has long been courted by the likes of Bayern Munich and Manchester United after another impressive season with the Champions League finalists, but despite the risk of losing him on a free transfer, Watzke is keen to keep the Poland star until his current deal expires in 2014.
"Our desire is still that he will play for us at least one more year until his contract runs out [on June 30, 2014]," he told Suddeutsche Zeitung.
Dortmund have already lost star playmaker Mario Gotze to Bundesliga champions Bayern after they matched his €37 million release clause, and Watzke has made it clear they will not offer players the same such deal in contracts in future.
He added: "After winning two championships and going through to the Champions League finals, we have reached a status where we expect every player to unconditionally commit to the club."
