Can't believe

England are already 1-0 up, and a win today will hand them the series. Can't believe this contest is more than halfway through already.
Explain the red coloured sentence of this paragraph. There is no Noun or pronoun before Can't believe, which creates difficulty to understand the sentence. Please give one more example of such a sentence.

This sounds like a transcript of something that perhaps a sports commentator said, or maybe something someone put on Twitter during the cricket. It's very simple. The missing word is "I" and it is implied. If I said to my friend "My bike has just been stolen for the third time this month! Can't believe it!"

In spoken English, we do this kind of thing all the time. "I had a dreadful meal at that pizza place last night. Never going there again!" Obviously, the full sentence would be "I am never going there again!" but it's omitted because it's quite clear that I'm talking about myself. I would not say "I had a dread meal at that pizza place last night. My mother is never going there again!"

Where did you read or hear this? In speech or informal writing like texting, this sort of thing happens- to understand it, simply insert the most likely noun or pronoun.

I read it in live cricket commentary at Live Cricket Scores | Cricket news, statistics | ESPN Cricinfo. A platform where written commentary is provided for every single ball.

Aha! There you go, then. As I said in my first response, it sounded like something from a commentary. Always remember that in spoken English, we don't always follow the rules of grammatical written English. A transcript of something which was said without a script (ie when a sports commentator is following the action and trying to describe it at the same time) will frequently have missing words, changes of direction halfway through a sentence, pauses in strange places etc.
