Messi vs. Ronaldo

In 2009 Real Madrid paid $120 million (then a record fee) to sign a ready-made superstar in an effort to keep pace with a Barcelona side that had won it all. In doing so, they sparked a rivalry like no other; Messi vs Ronaldo. The seasons that have followed have been truly spectacular, the battle for supremacy increasing in profile and intensity all the while. Their styles, personalities and soccering allegiances continue to divide opinion, but their dominance of the record books has now put one claim beyond debate -- this is soccer's greatest ever head-to-head. Acclaimed soccer writer Luca Caioli draws on invaluable testimonies from those closest to the two stars, with exclusive insights from friends, families, teammates and managers, to tell the inside story of this fascinating rivalry.
