revs high in top gear

hello got a mk2 1.8 and it seems like the revs run out before i get to top speed if you know what i mean , didnt do this at first but has got worse feels like i need another gear , anyone got any ideas thanks.

Do you mean that the engine is revving higher, without any commensurate increase in speed?  Which gears?  

From your vague description, it sounds like a slipping clutch?  

Agreed.

 

 

yes i thought clutch too but clutch doesnt ride hide , seems it only wants to do 120 now aswell .

i dont know how can i confirm clutch cheers.
