Nico Rosberg says he is hopeful of competing for the race win at the Monaco Grand Prix later this month.
The German has secured pole in each of the last two races - but has been unable to carry his pace over into race day as Mercedes continue to struggle with tyre degradation.
The German fell back from 1st to 9th at last month's race in Bahrain, while in Sunday's Grand Prix in Spain he dropped down to 6th from pole.
Mercedes should fare better at the Monaco Grand Prix later this month with tyre degradation much lower on the slower street circuit than at most other races.
Ferrari driver Fernando Alonso, who claimed 1st place on home soil on Sunday, believes Rosberg and team-mate Lewis Hamilton will be a force to be reckoned with in the principality.
While Rosberg said he was confident of not falling off the pace so quickly as in other races, he urged caution ahead of the race where overtaking borders on impossible.
"Maybe lack of race pace is not so detrimental there and we can finish higher up, but still the race is a bit of a concern," he said.
"[We need to do] a lot of work and a lot of head-scratching."
While Rosberg looks forward to being more competitive in Monaco, Hamilton, who dropped from 2nd to 12th in Spain, admits he is keen to resolve the car's deep-lying problems rather than hope for results on circuits that suit its strengths.
“I am not even thinking about Monaco. We have just got to digest what has happened in Spain," he said.
“Falling from second to 12th is a big drop. I need to go back with the team and really question all of the engineers.
“I want to put ideas into their heads and get ideas from them about what we can do to improve for the next time we go out.”
