Fernando Alonso has been left to rue the reliability issues Alpine have faced this season, following another retirement at the Abu Dhabi Grand Prix.
The Spaniard's final race for Alpine ended prematurely due to a suspected water leak.
The DNF ultimately denied the team the chance of finishing ahead of McLaren in the Constructors' Championship, in a year that Alonso previously said he's lost around 60 points due to "unacceptable" reliability.
"There are facts that this year they've been against us a little bit in car 14, six DNFs," Alonso told media, including RacingNews365.com.
"But also [the ones] where they don't count as a DNF, but they were DNF like in Australia qualifying [there was] a problem, a Sprint race in Austria where we didn't even start the race, and things like that.
"So, I think there are nine or 10 reliability issues, which at this level is obviously not acceptable."
Alonso was asked if he thinks this season has been similar to his stint with McLaren-Honda, however he believes it has been a lot more competitive with Alpine.
He added: "I think we've been more competitive this year. When we finished the race, it was more enjoyable than McLaren-Honda when we were always out of the points, so I will not compare."
