Borussia Dortmund may seek to re-sign Portsmouth midfielder Kevin-Prince Boateng.
BVB were priced out of a deal for Boateng last year by Tottenham, but coach Jürgen Klopp admits he remains a fan.
With Pompey desperate to sell to balance the books, Boateng could become available for a knockdown price.
"We had to keep him happy, but we just did not have the money, which was demanded by his club Tottenham. If we had the money tomorrow, he would be back tomorrow," said Klopp.
