You are talking exactly the way I thought about this game, too. I can openly admit that I took on a bet against my friend and he offered me some amazing odds when I bet that Liverpool is going to win with 2+ goals and Frankfurt is not going to lose. When someone offers you great odds you start talking yourself into it literally! 
On like you, I would want to talk myself out frm taking the bet, not except I've got that assurance from my guts and the teams to which am supporting are the better side in that fixture. Being offer an outrageous odd would immediately make me ask myself; what is it that he knows and I don't know? Is there a top man on the bench, perhaps suspened or have been injured during the training? Questions such as these would cloud my mind and in a way, am likely not going to take the bet. Rather, I'll enjoy the game by just watching and not having to favour any team. Quote
After 15 minutes it was 2:0 for Liverpool and I sent him some smileys and said "already shitting your pants?" haha, funny anecdote.
Definitely something anyone would do but, against Real Madrid in the UCL.. Real Madrid is the UCL and they've had a come back at the least possible time with a big team to get back into the league. I wouldn't let my adrenalin get the better of me should I bet against Real Madrid. haha, funny anecdote. Yes I see it the same way and I did of course do the basic checks whether some important guys are injured and so on. But in the end it is also a good friend and at times we bet against each others just for fun. If one loses, the friend wins. That's always better than losing against a bookmaker and the money is gone. Usually we spend it together going out for a night anyway having some food and drinks. It is more about those funny situation like the one I described when I wrote "already shitting your pants?"
We both were laughing about it in the end. He texted some very funny answer and that is what it actually is about. If I had to place my bets with a bookmaker, I would have chosen Napoli as the winner, but I would not have chosen Real Madrid as the winner. The 2:5 was too much and I doubt anyone who placed bets even got close to that result unless it was one of these "who cares, I am going for some crazy odds today". Real Madrid winning with 3+ in Liverpool after being 2 goals down, yeah...
You get my point! 
But one issue that Liverpool has now repeatedly been fighting with are those goalkeeper blackouts. They happen too often.
