"The gaffer is rotating the squad and both of us (Carvajal and Arbeloa) are trying to it difficult for him.
"Carlo has the final say and will make the decision, he's got us all on our toes.
"I'm happy with the opportunities, but I'm ambitious and fight and train hard every day to be able to play more."
