McLaren have revealed that they will not name their 2015 driver lineup before December 1.
Jenson Button and Kevin Magnussen are waiting on news of their futures as the Woking outfit reportedly attempt to negotiate a return for Fernando Alonso.
An announcement was expected prior to the last race of the current season in Abu Dhabi this weekend, but a McLaren statement has said that it will not be confirming the identities of their two drivers this month.
"Selecting the optimal driver lineup for a Formula 1 team is clearly an important process, and it is therefore one that requires precise and prolonged analysis," a McLaren statement read.
"That being the case, and in order to avoid distracting the race team from its primary objective during the final grand prix weekend of the season, which is to secure the best possible on-track results, we have decided to defer our final deliberations relating to our 2015 driver lineup until a date no earlier than Monday, December 1."
Alonso left McLaren seven years ago but is being tipped to return to partner Magnussen next season.
