Sergio Perez has called for a review into his and Red Bull's weekend in Australia, after coming home a distant second to Ferrari rival Charles Leclerc.
Perez was the lone RB18 at the chequered flag on Sunday after teammate Max Verstappen ground to a halt with a yet-to-be-confirmed technical issue.
However, despite Safety Car and Virtual Safety Car interruptions, the Mexican finished some 20 seconds adrift of Leclerc, with Ferrari holding a clear pace advantage over Red Bull across one lap and in race trim at Albert Park.
Perez thinks Red Bull made "fundamental" mistakes
Although he would not go into specifics, Perez pointed to "fundamental" points that Red Bull got wrong throughout the weekend and expects a busy couple of weeks before F1 returns to action in Imola.
"It was a good result, certainly, but [we've got] a lot of work to do," Perez told members of the press, including RacingNews365.com.
"I think at these first three races, we've been quite unlucky, with [the double DNF in] Bahrain, with [the Safety Car in] Jeddah, but today was a bit of a concern.
"I think we got a few things quite wrong, fundamentally, [so there are] a lot of things that we have to review going forward."

Perez and Red Bull to "come back stronger"
Pushed on what will be at the top of his and Red Bull's list going forward, Perez explained that there is plenty of "good information" to look through after implying a major car set-up split between himself and Verstappen.
"I think generally the direction we took with the car through the weekend; both cars went very different ways," he commented.
"I think we have good information to understand and hopefully come back stronger."
Perez holds fourth in the Drivers' standings, two places ahead of Verstappen, while Red Bull hold third in the Constructors' battle, behind Mercedes and Ferrari.
