Alves has ordered the Barcelona squad to stick together and ignore the "rockets" that have been thrown following two successive defeats.
He told El Mundo Deportivo: "We cannot doubt the work we are doing.
"If you worry about what is coming from the outside then you are lost. If doubts are left out we will continue to the top.
"The major thing is that (the negativity) should not affect the squad. We are alone."
"If we lose it's news all day," he added. "And if we lose twice rockets are thrown everywhere."
