Ferrari do not regret their failure to sign Lewis Hamilton for the 2021 season as they are confident Charles Leclerc can challenge the Formula One champion.

Hamilton has won six of his record-equalling seven world championships with Mercedes, although he has not yet committed to the Silver Arrows for the coming campaign.

A resolution is expected soon, but links to rivals Ferrari have never been far away.

A blockbuster move will not materialise on this occasion, however, as the Scuderia have secured Carlos Sainz Jr next to Leclerc in their 2021 line-up, replacing Sebastian Vettel.

And team principal Mattia Binotto is confident they have made the right move.

He told Sky Sports: "I don't think there will be regret because, at the end, when we took some decisions, we took them thinking they were the right decisions and today we have a fantastic driver like Charles, where we invested a lot as Ferrari.

"I think he's got a lot of talent. If he's got the right car, I'm pretty sure he can challenge Lewis Hamilton.

"We've made our choices and I think, together with Carlos, we are very strong. I don't think there will be any regret."

Although Leclerc - fourth two years ago with two wins to his name - would appear the obvious Ferrari contender, Binotto is not naming a "number one".

Sainz finished seven points better off than his new team-mate in 2020 while still with McLaren.

"There is not a number one and number two," Binotto said. "They will have equal opportunities - certainly at the start of the season. I'm pretty happy then that they are free to fight.

"I think what we have to do as usual is to optimise the team points, and when you optimise the team points, normally you are optimising the drivers' points as well. Team points is the number one.

"Later in the season, let's see how things will progress, let's see what objectives individual drivers can maybe achieve and if we need to adopt a different strategy, but at the start of the season, they will be free to fight."

Carlos Sainz compared Ferrari and McLaren to LaLiga heavyweights Real Madrid and Barcelona, and is confident of a successful transition to the Scuderia. 

The Spaniard spent the past two seasons at McLaren, making the podium on two occasions, but is Ferrari-bound for 2021, replacing Sebastian Vettel.

Sainz spoke about how the objective for both teams is to cut the gap to dominant Mercedes, while he feels the fact he will have raced for both teams proves he is doing something right in his career.

Asked by AS if racing for Ferrari is like playing for Real Madrid, the team Sainz supports, he replied: "It's one way of saying it…but McLaren is Barca, which is also a very good team to be on. 

"It cannot be compared, because in addition both are in a restructuring to try to dethrone Mercedes in the future. 

"But they are the two best teams in history and when you go from one to the other it means that you are doing something right in Formula One."

At Ferrari, Sainz is joining a team where the pressure is always on to be a success and internal politics have historically always been a lingering presence in the background.

But Sainz is confident of being able to bring a harmonious atmosphere like the one he was part of at McLaren.

"That I managed to do it at McLaren means I can do it at Ferrari. If I could create a good team, generate good dynamics at McLaren, why not do it at Ferrari? I can do it," he added. 

"I like the people out there, I like Mattia [Binotto, Ferrari team boss] and I like what I see, what we have talked about. 

"There was no hesitation when it came to signing the contract and going forward. In my head there is no possibility that this environment and similar situation cannot be generated. 

"If I could at McLaren, I can at Ferrari."

Sainz's predecessors at Ferrari Vettel and Fernando Alonso arrived with huge reputations as two of the most gifted drivers of their generations and with world titles to their name.

Neither man was able to end Ferrari's wait for a champion dating back to 2007 but Sainz believes it is wrong to judge their success at Maranello based on titles.

"They leave with a few victories and podiums, if you call that going empty…I only have two podiums," he said. 

"Are they leaving without a championship? Yes. But the same has happened to nineteen drivers, every season for the last 10, when Red Bull or Mercedes have dominated. 

"There are nineteen drivers a year who have gone empty, but I do not include those who have raced for Ferrari. Nobody leaves Ferrari empty."
