They might be the bitterest of rivals on the field, but Real Madrid quickly added their voice to the worldwide chorus offering their best wishes to Barcelona defender Eric Abidal.

The picture seen here was included in a message sent out on Madrid's official Twitter feed. The message read:

"Real Madrid squad wish to show their support to Eric Abidal. We are sure that everything will go well. Get well soon!"

Barcelona released a statement on their official website saying Abidal will be forced to undergo a liver transplant in the coming weeks.

The development comes after the French player had emergency surgery last March to remove a tumor from the same organ.
