Sergio Perez is poised to confirm a change to his management structure, amid emerging doubts about his future at McLaren.
Although the Mexican is closing in on a deal to remain at the team for 2014, the team has made it clear that it not yet seen enough to commit to a contract. That uncertainty, with team boss Martin Whitmarsh saying he wanted to see improvements from his new signing in Singapore this weekend, has prompted McLaren to consider other potential options, including Fernando Alonso.
It is believed Perez may be on the verge of appointing a new management company to replace compatriot Adrian Fernandez, who has guided Perez's career for some time. Former Indy car and sports car star Fernandez, who has regularly accompanied Perez at races, is a notable absentee in Singapore this weekend despite the speculation surrounding the Mexican's future.
Perez declined to elaborate on the situation when approached at the Marina Bay circuit, but he did stop short of denying that he and Fernandez may be about to part company. McLaren also did not wish to get involved in the matter, and made it clear that Perez's management situation was up to him.
Fernandez was unavailable for comment when contacted about the matter.
