Ricciardo, having run wide through the Turn 9 gravel early on, gradually drifted away from Red Bull team-mate Max Verstappen, but dropped a sizeable amount of time during the Virtual Safety Car period.

F1 next heads to Monaco in two weeks' time and Horner hopes Red Bull can take advantage of the famous Monte Carlo street circuit's twists and turns to be in the hunt for pole and victory.

"It is a little bit disheartening as I don't really know what I could have done more with what we have".

Red Bull team principal Christian Horner believes changes to the Formula 1 aerodynamic regulations in 2019 have been "rushed" and will "cost millions and millions of pounds" for the teams.

Ricciardo said he struggled with his auto despite recording the fastest lap of the race by over six tenths of a second in the closing stages. The team was confident that they had gained around half a second through upgrades for the Barcelona race.

But Horner remained coy on whether the RB14's updates will enable them to change the pecking order at the head of the field.

"Friday paints one picture but you are never really sure about what is going to happen", said Ricciardo.

Meanwhile on the other end of the garage, Max Verstappen stuck to the Supersoft for both runs.

"You never really know until qualifying".

"We both put good laps on the Supersofts in Q3".

"I still don't know what is the fastest tire to be honest", continued Verstappen.

Ricciardo has been able to make up for disappointing qualifying performances with some great race pace.

"We just don't have that power mode for Q3", Max Verstappen bemoaned. "I think Mercedes went on a soft - I haven't seen really but even for me it was a guess, so it's a bit tricky".

Many drivers were struggling to make the super-soft work at all on one qualifying lap and it looked as if teams would be trying to minimise running on what would before the weekend have been expected to be the qualifying tyre. I don't think many people will actually choose the Supersoft [for the race].

"I think a lot of people will choose a soft and a medium", he decided.

"And from Turn 7 to Turn 10 is also straight now so it's all a bit more painful for us and it just gets even harder".

"Add together with my final lap I couldn't continue".
