Stoffel Vandoorne has said that he is not doubting his abilities, despite a difficult opening pair of races in 2017.
The Belgian actually made his F1 debut in Bahrain a year ago, but 2017 is his first full season at McLaren-Honda.
In Australia and China, the obvious stand-out performer for the struggling team was Fernando Alonso.
Vandoorne, however, told Belgian broadcaster RTBF: "I do not doubt my abilities at all.
"On paper, it may not have been the two best weekends of my life, but I have no doubts at all. I know that when we get a weekend without problems, the result will be there.
"The most important thing for us right now is to bring updates for the car and show that our package is improving weekend after weekend."
McLaren are one of three pointless teams heading into the Bahrain Grand Prix.
