Although he's enjoying a "fantastic project" with McLaren-Honda, Fernando Alnoso says there is "temptation" to try other racing series.
The double World Champion is in the midst of arguably his most difficult season in Formula 1 as McLaren and new engine partner Honda struggle to get up to speed.
However, it's not the fact that he's managed just one point in nine races that has the Spaniard feeling downbeat. Rather, he says, it is today's Formula 1 and its limitating rules.
"I love motorsport, all the categories," he explained.
"It is true that F1 is not exactly the same, or as exciting as it was in the past – at least to me, to drive the cars two or three seconds faster than a GP2 car.
"Right now, there is huge motivation and a fantastic project that I am in right now with McLaren-Honda. My first go-kart was a McLaren-Honda replica and I am in a real McLaren-Honda, so I am enjoying this process of getting competitive starting from zero.
"But with no testing, with these tyres, with these limitations, with the calendar for example next year, there is the temptation for other categories, that is true."
