Ferrari president Luca di Montezemolo insists that Ferrari has to keep pushing during the final four races of the F1, despite team principal Stefano Domenicali revealing that work at Maranello is now focused firmly on 2014.

With hopes of the title now all but over, Ferrari's focus in the remaining four races is on ensuring it stays ahead of Mercedes and Lotus in the constructors' championship, with Fernando Alonso also seeking to wrap up second in the drivers' standings.

Despite the challenge ahead however, Domenicali says that Ferrari has now switched focus to 2014 in terms of work at the factory, with only limited updates to be introduced in the final races as the team seeks to see off the challenge of its rivals.

"We have already switched 100% the activity at home [to 2014]," he was quoted by ESPN. "We have still got something to bring to the track that we will try, but the technical office is completely dedicated to next year's project. That is very challenging for everyone.

"Lotus seems to have found a good qualifying pace, very close to ours and maybe a little bit better. They are also very good at managing the tyres, so if they qualify in front of us then it is difficult because either we do a good start and they are really difficult to handle.

"On the other hand Mercedes seems to have for sure a better qualifying pace, and if they are in front in the race with another competitor like Lotus in between it will be difficult. For this reason I believe they are both very strong competitors and we need to be second up until the end of the season."

Despite Domenicali's view however, president di Montezemolo was quick to stress that he didn't expect to see Ferrari ease up in the final races of the year.

"I read about assumed bellyaching or about the team concentrating only on 2014," he said. "I don't even want to hear that kind of talk: there are still four races to go where we will field Ferraris that are fighting for the podium with maximum determination from the drivers and the whole team.

"As for next season, there will be time enough to talk about it, and in fact I am pleased to see that the group dedicated to that task is working very hard with maximum concentration. Everyone is well aware what they must do."
