Azpilicueta was particularly critical of their thumping defeat at Sheffield United on Saturday.
He told chelseafc.com today: "When you are a player of Chelsea you have to give everything in every training session, in every game. Always Chelsea have had very good players, world-class players, new signings. We know that every day we have to fight for our place and the standards are high and we have to aim for the maximum.
"This ambition has to remain. We know that the squad we have at the moment is one that can achieve the targets for this season and then when next season comes we will take it as it comes. But the focus is on doing the best job we can in these weeks and getting the targets that we are aiming for."
