Former Red Bull driver Mark Webber has described Max Verstappen as being "a bit flaky" this season, saying he'd like to see him "on the road" more often.
Verstappen has had a disappointing first half of the season, with just 67 points from the first 11 races compared to teammate Daniel Ricciardo's 117. A series of retirements account for most of the gap, with reliability issues resulting in DNFs at three races and first lap collisions out of his control causing DNFs at another two.
But Webber points to Verstappen's performances during practice sessions and the build-up to races as an area to improve.
