Last year Valtteri Bottas helped team-mate Lewis Hamilton win his fifth World Championship in controversial circumstances.
Mercedes boss Toto Wolff ordered the Finn to give up his lead at the Russian Grand Prix to allow Hamilton to extend his gap over Sebastian Vettel.
Ferrari have come out and said Leclerc will help Vettel challenge for his fifth world title this year.
And Todt inclined that he had no problem with the team tactics, despite many fans believing it is against the spirit of racing.
“Sebastian Vettel, four-time world champion, one of the best drivers of the field. It will be very interesting to see,” Todt told Sky Sports.
“We come back to controversial questions, it is up to the team to decide on their team.
“If they both have the same cars then time will see how develops.
“It is his second season in Formula One for Charles Leclerc. He has been doing an excellent job so far in different categories.
“He was racing last year at Sauber with a Ferrari engine and he did extremely well. I think it is great that the top management at Ferrari gave him the chance.
“We know in Formula One there are two categories. You might be a talented driver but not have a competitive car.
“So it seems that the package is put together and time will tell how it works.”
Ferrari appointed Mattia Binotto as their new principal this year, replacing Maurizio Arrivabene, who paid the price for a 12-year title drought.
Binotto worked under Todt at the FIA and his former boss wishes him well.
“He is a great character. I remember I hired him and I think it is very nice to show how you can develop yourself in a company,” Todt added.
“He did a remarkable job as a director recently and he has been promoted as the team principal of Ferrari and I wish him well.
“Of course it is different but it seems Ferrari have been doing an excellent job. The driver line-up is quite interesting so let’s wait and see the first race in Melbourne.”
