Ferrari's Kimi Raikkonen says too many new tracks on the Formula One calendar "all look the same".
The 2016 calendar will feature a new race on the streets of Azerbaijan, while races in Abu Dhabi, Singapore and Russia have joined the calendar in recent years.
But Raikkonen believes the new circuits are too predictable and have many similar corners.
"When we go to a new track, we know what to expect," Raikkonen told Finnish publication Turun Sanomat.
"They all look the same. There are no trees or anything else in the landscape. Of course, each track is always a little bit different, and each corner at the track is a little bit different, but ultimately the new tracks are made up of Tilke corners."
Raikkonen said the Korean International Circuit, which was part of the Formula One calendar from 2010 to 2013, was "the worst" of the recent new circuits.
