Kimi key in driver merry-go-round

McLaren driver Juan Pablo Montoya has admitted he is unable to make a decision on his Formula One future while team-mate Kimi Raikkonen remains undecided on his plans for 2007.

Both drivers are out of contract at McLaren come the end of the season, but Montoya doubts he will have any concrete plans in place before Raikkonen, a Ferrari target, decides where his future lies.
