Former Real Madrid president Ramon Calderon is backing Joan Laporta for the Barcelona election.

Calderon held his position at the Estadio Santiago Bernabeu between 2006 and 2009, while Laporta was president at the Camp Nou between 2003 and 2010.

"Joan Laporta's victory in Barcelona's elections would be great news for Barcelona fans, and not so good news for his rivals in Spain and Europe," Calderon's first tweet read.

"As he is my friend, and I know he is looking forward to his return, I wish him success."

The ex-Real Madrid president then published a second tweet, explaining why the Barcelona presidential candidate is a good friend of his.

"A friend is the one who, in good times, is by your side only when you call him and, in bad times, always, even if you don't call him," Calderon's second tweet read.

"That has been Joan Laporta's behaviour towards me and, for that reason, football rivalries aside, I will always wish him well in life."
