Alonso hopes to keep Hamilton in his mirrors

Formula One championship leader Fernando Alonso will focus his attention on nearest rival Lewis Hamilton at this weekend's Singapore Grand Prix as the Spaniard knows it is impossible to watch everyone.

Ferrari's Alonso leads Hamilton by 37 points with seven rounds remaining but the Briton has hauled himself into contention by winning two of the last three races to loom large in the Spaniard's wing mirrors.

McLaren's Hamilton sits a point ahead of Kimi Raikkonen and two ahead of defending champion Sebastian Vettel whose Red Bull team mate Mark Webber is a further eight points adrift in fifth place.

Jenson Button is sixth in the other McLaren and, while he may be too far behind to mount a title challenge, his victory in Belgium two races ago means the team have won the last three races and are clearly the cars to beat.

"McLaren are favourites to win this week so we need to stop their domination. Hopefully, we have brought some new parts to the car since Monza and it means we can do well here and at the races after that," Alonso told reporters on Thursday.

"Everybody is strong at the moment and everybody is a contender. There are still five or six drivers that can fight for the title.

"Sure, Lewis is a strong driver and someone I respect as we know how good he can drive with a good car or a bad car and he is second in the standings.

"But it is hard to focus on five drivers at once, with the strategies and the stops, so it is best to be aware of the closest one and at the moment that is Lewis."
