David Ferrer's farewell tour ends this week in Madrid. It's a fitting place for the Spaniard to officially say goodbye to all his fans and friends. His friends are taking the time to say goodbye, too.

Madrid tournament organizers helped arrange a sendoff with the hashtag "#GraciasFerru".

Juan Martin del Potro took part:
