Borussia Dortmund are interested in Malaga midfielder Isco.

Isco, also a target for Tottenham and Arsenal, could be available in January with Malaga's finances still on a knife-edge.

Borussia Dortmund are eyeing Isco after selling Shinji Kagawa to Manchester United.

Isco's buyout clause is set at €21 million and Dortmund are willing to go to €15 million for the youngster.
