Real Madrid are preparing a bid for Borussia Dortmund star Pierre-Emerik Aubameyang.

AS says his start this season, bagging six goals in six games, has further boosted Los Blancos' interest and the French-born striker could be next on the Real Madrid galáctico list.

The two sides meet in the Champions League on Tuesday, with the Dortmund forward the in-form striker after scoring four goals in ten days, against Legia Warseaw, Wolfsburg and Freiburg.

When asked about a possible move to the Spanish capital the striker said: “I'm not going to talk about that", particularly in view of the fact that both sides, the strongest in the group, will look to inflict a psychological blow on each other.

But he has previously stated: “Before he died, in 2014, I promised my grandfather I would play for Madrid one day."
