Juan Pablo Montoya expects McLaren's resurgence to gather pace in this weekend's United States Grand Prix at Indianapolis.
Montoya's team-mate Kimi Raikkonen has stood on the podium at the past two grands prix after showing encouraging early pace at both Silverstone and Montreal.
That represents an improvement on the start of the season, when neither Raikkonen nor Montoya looked serious challengers.
Montoya believes McLaren can continue that positive progress this weekend at Indianapolis, where he is the only driver other than Michael Schumacher to have won a grand prix.
The 2000 winner, who crashed on lap one in Montreal, said: 'We should be very competitive. My car in race trim was very good in Canada and it was a bit annoying not to be able to show the pace.
'I think Kimi had a better qualifying car but I thought I could have a better race car. It was a bit frustrating from that point of view.
'That's the way racing goes and I think here it should be a strong race for us.
'I think the trend is we're getting better and better and better. It's a matter of trying to get a good qualifying lap.'
