Like Barca fans, Alves is a little anxious over delays regarding Guardiola's new contract.
The Brazilian said: "If we continue with this coach, we'll go far.
"Guardiola is a coach who knows good things and always passes them on. He is the key to the success of this team because he is able to get the best from each of us.
"With Guardiola, what is certain is that there will be no relaxation, because he always demands we maintain our ambition."
