Alonso still believes McLaren move is right

The French squad have won the first three races of the season in dominant style, allowing Alonso to take a commanding lead in the championship. The Spaniard, winner in Bahrain and Australia, has scored 28 points to his teammate Giancarlo Fisichella's 14.

McLaren's Kimi Raikkonen is tied on points with Fisichella, and his team trail Renault by 19 points in the teams' standings.

But despite Renault's impressive start, Alonso reckons McLaren will be the team to beat next season.

"McLaren have taken a big step forward. I'm convinced that there isn't another team around, able to make a car improve as quickly as them," Alonso told Gazzetta dello Sport.

"In 2007, the second year of the V8 era, they will be the best around, that's why I chose them."

Asked about his reasons to leave Renault, Alonso added: "The sensation that a cycle is coming to an end anyway. I and Renault came to F1 practically together.

"Now that I've won here there's little left to do."
