MANAMA, Bahrain -- Despite relatively high levels of tyre degradation, the fastest strategy at the Bahrain Grand Prix is expected to be a one-stopper. However, it requires starting on the medium compound tyre -- an option not available to the top nine drivers and Romain Grosjean (who will start 11th after a penalty), who are all required to start on the soft having used that compound in Q2 -- before switching to the hard. A one-stop is also possible starting on the softs and moving to the hards, but it is not as fast.
