Borussia Dortmund are eyeing Real Madrid midfielder Sergio Arribas.

Arribas is set to leave Real Madrid this summer after outgrowing the Castilla team.

Beyond a Primera Liga move, the midfielder is also attracting interest from Borussia Dortmund.

Last season with Castilla, Arribas scored 21 goals and distributed 7 assists in the 40 games he played.

Ruhr Nachrichten says Dortmund are keen and are open to taking the 21 year-old on an initial season-long loan.
