Carlos Sainz does not expect his Toro Rosso team to stay ahead of Red Bull for much longer, as he reckons his team's focus is elsewhere.
Toro Rosso has emerged as the strongest of the Red Bull-owned teams in the first two races of the season, as its sister squad has struggled with its chassis and the Renault engine.
Sainz and teammate Max Verstappen have helped place Toro Rosso in fifth position in the standings, one point ahead of Red Bull.
But the Spaniard believes Toro Rosso's battle is not with Red Bull.
"I think they had a lot of issues in Malaysia and altogether they made them a bit slower than they should be," said Sainz.
"But Red Bull, I don't think about them.
"They should be ahead of us. It's a bit like McLaren in the end. All these teams should be in front. We just need to use these opportunities when they fail to be in front of them.
"There is a very interesting fight between Sauber, Lotus and us. When a Red Bull struggles they are with us, but I expect them to be in front in the coming races."
Apart from Lotus and Sauber, Sainz thinks Toro Rosso can set its sights on Williams, especially if Renault takes more steps forward in terms of top speed.
"The car feels very nice to drive, but again, this is just the beginning of the year," he added.
"Our target is to use these opportunities at the beginning of the year to get a lot of points, like Force India did last year for example.
"I see Red Bull more of a threat to be in front. I feel we have a great car in the corners.
"We are at Williams' level in terms of downforce and corner speed. We just need the top speed and hopefully that will come during the year and we can start fighting them."
