Do I need a new clutch?

[Nathan1305]

Want to replace my clutch at the end of the month but before I spend loads of money getting it done I want to make sure it needs replacing.

These are the issues I'm having:

When I pull away it's a little slow and doesn't have a strong pull.

And when I'm accelerating quickly the revs pick up but my speed doesn't.

Is this definitely in need of a new clutch?

Thanks
