Gasly finished 11th having started ninth, one of two drivers on the soft tyres.
“He did a good job in the first stint on the red tyre,” Horner told Sky.
Horner: “And then we got him track position.”
Horner: “And then lost out to the other guys as well.”
Gasly was passed by Ricciardo and lost places to Kimi Raikkonen and Nico Hulkenberg.
“It’s frustrating not to have that car in the points.”
Horner: “He drove the wheels off the car, another very mature drive.”
Horner: “But hopefully it’s in the pipeline.”
