Billionaire Jorge Mas persuaded the world¡¯s biggest soccer star to join a bottom-of-the-barrel team that¡¯s languishing in last place in its league.

The lynchpin of his strategy was signing Messi to a contract that jettisoned a traditional cash-for-services agreement in favor of revenue sharing accords and an equity stake in the team ¡ª a deal-making strategy closer to Wall Street¡¯s playbook.
