Clutch issue?

Hi, 

New to the forum so thanks in advance for your expert opinions on the subject.

I believe my 2014 Octavia may have a clutch issue, when pedal is in neutral and clutch is depressed and released there are no noises, when 1st gear is selected there is no noise on depression but on engaging the clutch at low revs I get a squeal, if I take off with revs around 1500rpm+ there is no squeal, there are also no noises throughout any other of the gear changes.

I'm thinking release bearing but if it is would I not get any noises through other changes and also pressing and releasing clutch in neutral?

Thanks James

1.6tdi Octavia.
