Hamilton: It is all a psychological game and winning has a positive effect on me 5 May, 2014 Lewis Hamilton heads to Barcelona seeking to extend the psychological advantage he has attained with three wins in a row, but at the same time is wary of his Mercedes teammate and other rivals who are sure to not make his weekend in Spain an easy one. Speaking ahead of the Spanish Grand Prix, Hamilton said, “In sports, it is all a psychological game and [in] getting good results you cannot measure what effect that has on people. But I know how positive it is on me.” Mercedes have given their drivers a handy race car in the dominant W05 which has won all four races so far this season, thus Hamilton knows that his team colleague and career long rival Nico Rosberg, who leads the championship standings, is the man to beat. “Nico will be massively quick at every race we go to. He is still leading the championship, isn’t he?” mused Hamilton. But the 2008 Formula 1 world champion admits that last time out, in China, he did all he could to drive home his advantage and set the marker within the Silver Arrows squad. “I was determined to make sure that in China we were not close, like we were [in Bahrain]. It was definitely feeling a bit more like it was in Malaysia. I am going to keep on working and keep with the approach I have, because it is working perfectly for me,” revealed Hamilton. Despite the dominance shown early on in the season, Hamilton remains cautious and even wary of what can happen as there is still a long way to go in the championship. “There are so many races to go, so you cannot predict what is going to happen. Ferrari took a big step. They are not the same pace as us, but to go from 10th [in Bahrain] to be third [in China] is quite impressive,” acknowledged the Briton. “Renault will also improve their engine for next race. We cannot stand still. We have to keep improving, and I am sure we will,” added Hamilton, who will be starting his 134th grand prix this weekend when he lines up on the grid at Circuit de Catalunya and will be looking to add to his 25 Formula 1 career victories on the day.
