Oct.8 (GMM) Despite earlier alluding to his position of inequality at McLaren, Fernando Alonso on Sunday said he is expecting to be given a fair chance of beating Lewis Hamilton to the world championship in Brazil.

The Spaniard told journalists from his native country after qualifying fourth on Saturday that he suspected he had driven with detrimental tyre pressures.

"I think they are still investigating but I think the tyre pressures were quite high, more than normal," Alonso, 26, said.

Now just four points behind his teammate with one race to go, however, he suspects that the Woking based team led by Ron Dennis will now give him equal treatment.

"Maybe it was just by accident that something went wrong and in Brazil it will be fine," he said after finishing second in China.

"I think we will have equality."

Alonso, however, maintains that the second part of the year for him at McLaren has and will continue to be "difficult".

"There is no problem, but we know that it is never going to be a favourable situation towards me," he told Spanish reporters in Shanghai.

"The first step (in Brazil) will be to have a qualifying without problems. I hope I am able to fight for the pole position, because that is one of the few options I have to win (the championship)."
