Then I really do doubt it needs replacing at the moment, they are just like that.
You can just try the clutch slipping test to see if it is.

2 methods, worth doing both as both show different things.
first on is put it in third gear, and fromo a stand still gently pull away, you'll need some revs but not redlining it, if that makes sense. just a little more than normal. if the clutch is good the car should pull away, albeit with a little juddering and shaking. if the clutch is going it will really struggle or stall completely.
the other test i'm not as familiar with but others use it on here, if i remember rightly, sit the car in 4th gear and drive at around 30 or 40 mph, then on a straight bit of road with no one around, drop it straight into 6th and floor the accelerator pedal. the revs should drop and the car will slowly creep up the revs and the speed.
if the clutch is going the revs will bounce really high then drop. if that makes sense.
