Pierre-Emerick Aubameyang's mother says her son has harboured dreams of playing for Real Madrid since childhood.

The Borussia Dortmund star has a contract at Signal Iduna Park until 2020, but has spoken in the past of a desire to one day play for the Santiago Bernabeu outfit. 

He has also been linked with Barcelona, but if it came down to a choice between the two Spanish giants, Aubameyang's mum Margarita Crespo says there would be no contest.

"He promised his grandfather that he would play for Real Madrid and since he was a little boy he spoke about Madrid and never about Barcelona," she is quoted as saying by AS.  "My family have always been Real Madrid and I would like to see him in white.

"A move to Madrid would be lovely, but at the moment he is doing well at Dortmund and we will have to see what happens."
