Jerez: Ferrari's Kimi Raikkonen was fastest in the final morning of pre-season testing in Jerez yesterday as McLaren and Red Bull's hopes for a problem free day were dashed. Jenson Button twice failed to get beyond the pitlane as a nightmare week for the new McLaren-Honda partnership continued.

McLaren racing director Eric Boullier warned on Tuesday that any more setbacks in testing would delay their chances of being competitive once the season gets underway in six weeks' time.
However, Button managed just seven laps yesterday morning to take the team's total for the week to just 51, the same number as world champion Lewis Hamilton completed before lunch despite suffering a spin earlier in the day.
Red Bull haven't faired much better and Daniil Kyvat managed just eight laps before being brought to a halt on track by a power unit problem.
