Mercedes motorsport boss Toto Wolff has admitted the team will need to do 'significantly better' in Monaco.

Nico Rosberg and Lewis Hamilton both qualified well for the Spanish Grand Prix last Sunday, with the Brackley-based outfit locking out the front row.

However race day was another matter entirely and tyre problems left both men struggling, Rosberg coming home sixth, while Hamilton finished outside the points in twelfth.

Looking to Monaco, Wolff warned that there is no room for complacency.

"Monaco is the most famous race in our sport and a special moment of every F1 season. The narrow streets will give our drivers the perfect opportunity to display their talents and, historically, the team's cars have performed strongly there in terms of pure speed," he stated ahead of the sixth round in the F1 2013 World Championship.

"However, it is clear to everybody in the team that, while we have a strong car right now, we are not able to use that performance properly on Sunday afternoon.

"[Furthermore] although overtaking in Monaco is difficult, we cannot afford to be complacent in terms of tyre management and we will need to do significantly better than we managed in Barcelona in order to score a strong result. We have only scored points with one of our cars at the past three races and this is something we must improve quickly, beginning next weekend in Monte-Carlo."
