Barcelona not yet champions, warns Alves
Barca go into the winter break 13 points clear of Real Madrid at the top of the Liga table.
"The gap is more than considerable," he said.
"But we should remain grounded as we still have many games left and the championship is far from over. I'm not surprised by our results so far.
"We are reaping the fruits of our labour. We worked hard, and the results are following."
