I messenged them last night via facebook and got the following reply
Hi Trish, UEFA sell the Semi-Finals and Finals separate to the rest of the tournament. Our understanding is there is not a broadcaster for Australia. We have tried to make a last ditch push to attain the rights for the Semi Final however no luck.
You may be able to view on UEFA TV or a club channel, however unfortunately we haven’t had a response from them as to where we can direct our customers.
We apologise for the inconvenience and hope you can find the match!
I said that was a shame
(as like all of us here, I had subscribed for the sole purpose of watching the Chelsea FCW games)
We agree Trish. We were hoping to work with the competition last minute but unfortunately due to the way it’s split up, we were unable to.
I did however watch the full game via the Chelsea YouTube channel.
