Transfer Market Los Blancos must be informed of interest

Aubameyang dedicates Bernabeu goal to late grandfather

"I still want to play for Real, it's a promise I made to my grandfather,"

The healthy relationship between Real Madrid and Borussia Dortmund has been strengthened by the Spanish side striking a deal to give them an option on their most important players.

At the Estadio Santiago Bernabeu, they played out an exciting 2-2 draw on the final match day of group stage action, a result which was enough to see the Bundesliga outfit top the section.

The agreement reached between the sides means that Borussia Dortmund will not allow one of their major stars to move to another side without first informing Real Madrid of another club's interest in their players, specifically Pierre-Emerick Aubameyang, Julian Weigl and Ousmane Dembele, who are of particular interest to Los Blancos.

The friendship that exists between Florentino Perez and Reinhard Rauball is a key contributor to this agreement, which has been in evidence in previous summer transfer windows.

For example, last summer, Borussia Dortmund informed Real's hierarchy that Manchester City were very keen on bringing Ilkay Gundogan to the Etihad Stadium, having been aware that the Spanish side had been interested in the midfielder in the past.

After Real Madrid informed the Westfalenstadion club that they had no intention of tabling an offer of their own for the Germany international, he made the move to Pep Guardiola's side.

The friendship and understanding between both clubs has continually resulted in Aubameyang being linked with a switch to the Estadio Santiago Bernabeu.

It is believed that the agreement means that if the Gabonese forward does eventually leave Dortmund, the only destination for him will be the Spanish capital.
