Ferrari Team Principal Frederic Vasseur has claimed Silverstone will be "much more demanding" for the team as it looks to repeat its Austrian Grand Prix podium.
The finished second fastest at the Red Bull Ring on pace after it introduced further updates to its car, following a disappointing start to the year.
While Leclerc could not challenge Max Verstappen on ultimate race pace, he maintained second without being challenged and broke the Dutchman's incredible streak of consecutive laps led - a string that had been active since Miami.
Leclerc's teammate Carlos Sainz was unable to shadow him after losing places during a Virtual Safety Car, a strategic error which he ultimately believes prevented him from finishing on the podium.
Speaking to Sky Sports F1, Vasseur insisted consistency between stint lengths and tyre compounds had improved, explaining: "It was much better in Austria and Canada, we were consistent and the delta from qualifying to the race was okay.
"But it's much more demanding in Silverstone, and it will be another challenge."

Vasseur: Difficult to draw conclusions from long runs
Ferrari only had Carlos Sainz out on track during FP2 long runs after Charles Leclerc suffered an electrical problem which consigned him to the garage.
Leclerc managed to set the fastest lap of final practice, though was unable to catch up on track time as rain fell midway through the session, leaving Ferrari in the dark.
"We had only one car yesterday on the long stint and it was difficult for us to draw a conclusion," added Vasseur.
"But what is true is that Silverstone is the most demanding track of the season for the tyres and and we know that it will be a challenge for us and for everybody."
