Borussia Dortmund chief: 'No Robert Lewandowski exit clause'

Borussia Dortmund general manager Hans-Joachim Watzke has revealed that the club are confident of keeping striker Robert Lewandowski because he does not have an exit clause in his contract.

The Polish hitman has been linked with a number of Europe's elite clubs, and scored four times on Wednesday night as the Bundesliga outfit thrashed Real Madrid 4-1 in the first leg of their Champions League semi-final clash.

With the Germans forced to admit losing to Mario Gotze at the end of the season to Bayern Munich earlier this week, Watzke is confident that the same will not happen to Lewandowski.

"Robert has a contract until 2014 and there is no exit clause like with Mario Gotze," said Watzke.

"It is our explicit wish to keep him until 2014. That is why we are saying no to a transfer fee."

Lewandowski has scored 33 goals in 42 appearances for Dortmund this season
