1st to 2nd gear squeak

Hello,
Hopefully a quick fix with grease but just to check..
When I change from 1st gear to 2nd gear only, the rest are fine, (Car running or off) and with the clutch compressed all the time, I get a metal on metal type squeak. I'm sure it's not the gearbox but just some linkage somewhere that needs grease. Can someone confirm or shoot down my theory ? Maybe know what linkage would need greasing ?

Thanks in advance!
