The midfielder has voiced his happiness with his side's win over Real Betis, and stated that los Blancos' ability to perform when it really matters has helped them to top spot
The Blancos struggled at times against Betis, but Cristiano Ronaldo eventually helped them to take all three points with his second goal of the evening in the 73rd minute.
"We're leaders because we respond well in complicated fixtures, such as the ones in Vallecas and Getafe, and now versus Betis," Granero told the official Real Madrid website.
"We knew the match would be complicated. Betis put pressure in attack and didn't let us play our game.
"We're in good form and top the table, but there are still a lot of games left."
Real Madrid sit top of the Primera Division with 70 points from 26 games.
