Max Verstappen has raised concerns about Baku's kerbs and pit exit after Friday practice, saying the drivers need to discuss both with the FIA.

Loose kerbs delayed GP2's qualifying session, which was supposed to be held between FP1 and FP2. That delay was prompted by the discovery that 90 percent of the left rear tyres had suffered damage on the kerbs, leading to FIA race director Charlie Whiting to conduct a track inspection.

The kerbs in question were welded down in time for FP2 to begin, though one still appeared to be loose in the subsequent session. Verstappen thinks that, and Baku's pit lane exit, needs a closer inspection.

Asked if he considered the kerbing to be dangerous, he said: "Yeah, some kerbs are coming off I heard. I think Sebastian [Vettel], I saw him come over the kerb and the kerb came up, so yeah we need to have a discussion. Maybe the exit of the pit lane is also not ideal so maybe open it up a little bit."

The Red Bull driver enjoyed his first day at the Baku City Circuit, however, though he thinks the narrow run-off areas in some places could cause problems for drivers who push the limits of the track too far.

"I think in general it's quite OK to drive. Just sometimes the run-off areas are a bit tight, like I went wide in Turn 3 and I had to reverse twice to get out of it again. That's not ideal but in general the track itself is quite fun to drive."
