Real Madrid won the league title last season, overtaking Barcelona in manager Pep Guardiola's final season running the team. Jose Mourinho's squad set a number of records along the way, including points, goals and goal difference.
This season, Barca will find their revenge under new manager Tito Vilanova.
Granted, players like Xavi and Carles Puyol are aging, and their powers are diminishing. But Andres Iniesta's importance continues to grow, and as he showed with Spain this summer, he's capable of being the key man in a championship side.
Barca also reinforced the squad with full-back Jordi Alba and midfielder Alex Song. David Villa's return from injury will be like another signing.
Real, meanwhile, have only signed Croatian midfielder Luka Modric so far. Will he really be enough, and will he be able to fit into the squad right away?
While Real answer those questions, Barca could be pulling away up the table.
