Charles Leclerc has questioned Ferrari's strategy for the Hungarian Grand Prix after dubbing his sixth-place finish as a "disaster".
A decision to put on the hard-compound tyre brought an abrupt end to Leclerc's hopes of winning the race, conceding position to Red Bull's Max Verstappen – who now sits 80-points clear in the championship standings after another victory.
Performances from others on the grid had already shown that the hard compound tyre was not competitive in Sunday's race but Ferrari, having used the medium compound twice, elected to take the hard rather than push out a longer stint before taking the softs.
That decision proved to be the undoing of Ferrari's hopes in what was an afternoon to forget, with neither driver finishing in the podium spots despite starting second and third on the grid.
Leclerc, who took full responsibility for his crash in the French Grand Prix a week ago, was asked whether he could explain the team strategy and says questions will be asked during a debrief.
"We need to speak with the team and understand the thought behind putting on the hard because I felt very strong on the medium, everything was under control," he told Sky Sports.
"For some reason, I don’t know what, we needed to go on the hards. I said on the radio that I was very comfortable on the medium and I wanted to go for as long as possible on those tyres because the feeling was good.
"I don't know why we took we took a different decision. Honestly, the pace on my side I was pretty happy with.
"The only thing is that obviously everyone will remember the last part of the race which was a disaster for me, especially the hard, that's why I lost the race.
"I lost 20 seconds with the pit, another maybe six seconds on five laps on the hard because I was all over the place with this tyre and yeah, that's where we lost our race."
Leclerc's teammate Carlos Sainz was equally disappointed and says he simply did not have a car capable of mounting a challenge.
"We clearly struggled as a team. Today, we're a bit puzzled because we expected to have good race pace coming from Friday, but it's clear that these lower temperatures, the track condition changes, there was something going on with the car and the tyres," he told Sky Sports.
"We were not fast. It's something to analyse, to look back, regroup, see what we did wrong for these kinds of conditions and come back after the summer break with a better package."
Mercedes team principal Toto Wolff defended Ferrari's tyre strategy and believes it was the only call they could have made.
"I think they had no option. They had only hard and soft left, for the soft it was too early, so it was only the hard," he said to Sky Sports.
"The mistake I think happened on Friday or Saturday, not to carry over a new medium."
