What to look for in the season opener

On the eve of the first race of the Formula 1 season, former grand prix winner and BBC pundit David Coulthard looks ahead to what might happen and who might shine in Bahrain.

A new season begins this weekend in Bahrain, and there's a lot of unanswered questions that will be asked of teams, cars and drivers.

I can't remember the last time there was so much rumour, speculation and unknowns going into the opening round as there is right now. At the end of Sunday night there'll be someone giving it, "I told you so" and others shrugging, "We didn't optimise our car".
