ITALY, Monza - Fernando Alonso insists Ferrari must plan to win more grands prix in 2012 if it wants to claim the Formula 1 title.Alonso said it might be possible for him to defend his 37 point lead in the drivers' chase simply by remaining on the podium at the remaining races of the season.'37 POINTS IS NOTHING'He said during a media event in Spain: "Managing this points gap is going to be hard, because I think everyone is going to be on the attack."The whole situation can change in one race that goes wrong. So we have to keep developing, working hard, trying to win races."We can't be thinking about being fourth or fifth, or doing podiums, or how to manage (the points gap), we have to be thinking of winning races. Thirty seven points is nothing," he insisted.Alonso said Ferrari is bringing developments to the F2012 package not only next weekend in Singapore, but also the subsequent races in Japan and Korea.Alonso was reluctant to talk about the future, even when asked what his relationship is like with Sergio Perez.Reports had linked the rookie with a move to Ferrari in 2013."I have nothing to say, especially in response to a report or a newspaper. The relationship (with Perez) is great, as it is with everyone else," said Alonso.
