The game has an auto clutch driving help, (options -> player). I haven't used it in a while, but i remember it working ok with dfp, which also did not have a clutch pedal.
Auto clutch operates the clutch for you in time with the gearchanges. It will not do any rev-matching for you. Also as the computer assisted clucth has a ramp (not on/off), your clutch will burn if you don't lift off the gas pedal when shifting up.
