Iniesta key for Barcelona in 'clasico' against Madrid (The Associated Press)

Barcelona's chances of winning the Spanish league this season could be determined by whether Andres Iniesta is fit to play in Saturday's ''clasico'' against Real Madrid. Having Iniesta available this weekend at Camp Nou could make the difference between clinching a third straight title or seeing Madrid snap a four-year winless drought. Barcelona has been struggling without the midfielder, and another setback could leave the team nine points behind and in a difficult position to fight for the title.
