MEXICO CITY • Red Bull are prepared to wait for Daniel Ricciardo to decide his Formula One future but have Spaniard Carlos Sainz as a "safety net" if the Australian opts to leave after next year, team boss Christian Horner said on Monday.
He told reporters at the Mexican Grand Prix that he wanted Ricciardo to stay alongside Dutch 20-year-old Max Verstappen, who has a long-term contract.
The Australian will be in the final season of a five-year deal next year and has been linked to both Mercedes and Ferrari.
"The next move he makes at 28 years of age is a very important one for him. So of course I'm sure he's going to take the time to make sure the decision is right for him," said Horner. "But he knows the intent very clearly, and I've discussed it with him, is that we want him in the team. If that takes another six months, then so be it."
Verstappen won the race at the Autodromo Hermanos Rodriguez, his second victory of the season, while Ricciardo celebrated victory in Azerbaijan in June.
The Australian's race on Sunday ended after barely a handful of laps because of a turbo problem.
"I think he's keen to see what engine performance looks like next year, which is understandable," said Horner.
Red Bull used Renault engines. While the former champions have won three times this year and taken more points than Ferrari in recent races, they have also suffered frequent failures.
"He knows how we go about our racing and how we treat the two drivers, which he's extremely comfortable and happy with," Horner said of Ricciardo.
"I think, as his character has developed and as his personality has come across, he sees the fit between Daniel Ricciardo and Red Bull.
"I think he sees the capability that we have within the team. And I think he's very happy in the team."
Asked what would happen if Ricciardo did leave, Horner said Red Bull were prepared for that.
"That's why we kept Carlos Sainz on loan, that's why we have options around us. We have a safety net but our No. 1 objective is to retain the (driver) pairing that we have," he said.
Sainz has been loaned from Toro Rosso to Renault as part of an engine deal that allowed the Red Bull-owned team to end a contract with the French manufacturer and partner Honda next season.
