Barcelona coach Tito Vilanova stands by his rotation policy.
Both Cesc Fabregas and Andres Iniesta have complained about being on the bench this season.
"We rotate the players as much as we can, so that the players can stay in form throughout the whole season. We try to do it for everyone", said Vilanova, who also has to think about internationals.
"The national managers want to pick the best players. They have to win and their job isn't easy either. But we have to evaluate the condition of the players and make sure they don't end up accumulating too many games".
