Barca returned to winning ways on Sunday with victory over Almeria.
"We had chances to score more goals, but Almería defended well," said Alexis.
"We secured three more points and now we're just one behind Real Madrid. The result from the Madrid derby was very good for us, but the most important thing is that we did our job well.
"We have to try and get the top spot of the table back as soon as possible."
