BBC Sport's Sarah Holt in Singapore: "The McLaren drivers sat tight until the very closing stages of first practice. The team have what they are describing as a 'big upgrade' in Singapore and are confident about their potential. Lewis Hamilton says: 'I think we are back on the pace and others have also backed up.' Does he reckon McLaren will get blown away by Red and Ferrari on Singapore's high-downforce circuit? 'I'm not expecting it,' he says. 'It's known that when they put more downforce on they go quicker but they were gaining a huge amount from two particular parts of the front wing and the floor. They were potentially illegal so the rules were changed and I think they will have lost the advantage that they had.'"
