Real Madrid star Cristiano Ronaldo believes Wednesday's 4-1 win over Atletico Madrid was a vital step towards claiming the La Liga title.
The Portugal international grabbed his seventh hat-trick of the 2011-12 season, before Jose Callejon helped to make the result even more expressive with a goal of his own.
Radamel Falcao had earlier drawn Atletico level.
The victory allowed Madrid to maintain the four-point gap between themselves and Barcelona at the top of the table, and Ronaldo believes that his side have taken an important step towards winning the league.
"There is a lot left, but winning La Liga has got closer now. Losing is not in my vocabulary," Ronaldo said.
"There was pressure on us because we knew Barcelona had won their match. We are still four points clear."
Ronaldo said he was delighted to have taken his league tally to 40 goals following Wednesday's hat-trick.
"I am very happy to have scored and picked up an assist," he said. "We have to continue like this.
"I am very happy, but without my team-mates I could not have done it.
"We knew this was going to be a tough match, but we gave a good account of ourselves against a very strong Atletico side."
Ronaldo has now scored 52 goals in all competitions following Wednesday's triple, and became the first player to score 20 goals away from home in a single La Liga season.
