Charles Leclerc has suggested that there is more to come from Red Bull and Max Verstappen after Ferrari topped the Free Practice 2 timesheets at the French Grand Prix.
Ferrari's Carlos Sainz was the fastest in the qualifying simulations at Circuit Paul Ricard, one tenth of a second ahead of teammate Leclerc.
Leclerc's championship rival, Verstappen, was third in the session and half a second off the pace.
Speaking after FP2, Leclerc was buoyed by the pace of the Ferrari F1-75, but expressed his surprise at Red Bull's practice programme.
"It was a good Friday, but we still have to work on the car a little bit for tomorrow," Leclerc told Sky Sports F1.
"It's very difficult to understand because it felt like Red Bull is doing something different to us on Friday, but we're focusing on ourselves.
"The feeling is good, so we just need to put everything together and the pace is in the car."

Leclerc keen to see what Red Bull can do
Red Bull had a low-key day of running in Friday practice; Verstappen's flying laps appeared hampered with minor understeer issues, whilst Sergio Perez never set a representative flying lap, finishing in 10th place.
Both Verstappen and Red Bull Team Principal Christian Horner expressed their confidence in their pace on the longer runs, something which Leclerc agreed with.
"Max seems to be particularly quick today on the high fuel so I don't know how much fuel they were running, that is a big question mark... Let's see tomorrow," Leclerc added.
"I believe the pace [is] in the car, we just need to focus on ourselves and if we do that perfectly then we will be fighting for the win."
