A downbeat Toto Wolff says his team remain in "no man's land" following the Miami Grand Prix weekend, with Mercedes finishing third-best behind Red Bull and Ferrari.
George Russell and Lewis Hamilton placed fifth and sixth respectively at the chequered flag on Sunday, after Russell was able to pass Hamilton thanks to a late Safety Car.
But there was frustration for Wolff post-race, with the team appearing to be far quicker during Friday's practice sessions than they were in qualifying and the race.
Wolff: We need to dissect what happened
"George stayed out for a long time as we were betting on a Safety Car for him and that materialised, coming from nowhere, and it went against Lewis," explained Wolff, speaking to Sky Sports F1.
"We lost the position there but, at the end of the day, there is no 'happy' or 'unhappy' at the moment. It's just a bit dull, as we are the third quickest on the road – we're in a no man's land.
"We had a good Friday; we need to dissect why that was and then come back."

Mercedes already have a mountain to climb
Mercedes will head into the upcoming Spanish Grand Prix 62 points behind Ferrari and with plenty of ground to make up.
"This is where we are," added Wolff, giving a blunt assessment of Mercedes' position.
"We are not as quick in qualifying and we go back to where we are, and that is behind the Red Bulls and Ferraris. We will be looking at all the data we have, that we have generated, and try to find out [why].
"We had really good sessions on Friday with quick laps, and we need to dissect why that is, because we are not on top of it at the moment."
