That player just won the bet. He must of known sheffield wasnt going to do anything to liverpool in the first half to place such a wager like this.

I think it could be the largest bet in their sportsbook. But according to one of the moderators on chat there was a 52btc placed but they can not disclose who this player is. Just as this one they want to keep bettors privacy like this unknown to the public. Which is understandable in these times of scammers and con artists all over the place.
