BARCELONA, Spain -- Midfielder Andres Iniesta has been left out of Barcelona's squad for Sunday's visit to Villarreal in the Spanish league.

Barcelona says coach Luis Enrique took the decision because of ''minor fitness concerns.''

The 31-year-old Iniesta is Barcelona's top playmaker in midfield. He helped the Catalan club beat Arsenal 3-1 on Wednesday to advance to the Champions League quarterfinals.
