Hertha Berlin chief Dieter Hoeness admits they may sell players to fund a permanent deal for on-loan Liverpool striker Andrei Voronin.

[Selling star players] is always a possibility so that we can fund new signings," he said.

"By selling, we have the chance to build our squad.

"We can sell players and then spend smaller sums on quality new signings - it gives us a way forwards for the future."
