Theres is a couple of things you can check/try before going to the expense of changing the clutch. Firstly l would bleed the hydraulic system and then with someone in the car pressing the pedal up and down, from under the car check the movement of the clutch lever arm (its comes out of the bell housing on the drivers side) to ensure it is returning properly. If not it may well be lack of lubrication on either the spigot shaft that the thrust bearing slides on or the ball pivot of the clutch arm. The latter could probably lubricated as is but the spigot shaft will need the box removed. Its a tricky problem and really the clutch condition can only be determined by a physical inspection once removed. Sometimes when left standing for long periods the linings de-laminate, not immediately but after being used for a short period, sadly this may be the case which once again can only be identified by removal.
