2008 Freelander 2 diesel clutch

Hi all help needed asap drove my 2008 Freelander 2 2.2 diesel the other day and clutch pedal went down and stayed down. From looking on forums I've changed the master cylinder but still no pressure on the pedal, still at the ground. Tried normal bleeding and I can get a small bit of pressure but not much.no leaks and fluid fresh. Any ideas how to bleed it properly as I'm obviously doing something wrong. Pictures if possible so I know where I'm working.matter of urgency as I don't like walking.
Thanx in advance.

Are you 100% sure it's not loose fluid?
The concentric slave is the most likely place for there to be an issue, but it would drip fluid from below the bell housing.

No 100% no fluid loss, I emptied it and put all new fluid in to see if it could be due to loss of fluid but it's still the same as what it was and when the clutch pedal hit the floor it was the first thing I checked as I assumed I wasn't vigilant in checking the levels.so when the levels were ok I assumed it was the master cylinder so I changed that. I'm going to try reverse bleeding and hope that works or is there anything else I can try?? Thankyou for your prompt response too
