It won't be fair to underestimate a team before the game kick-off, maybe lets wait for the ball to bounce then we can say Tottenham Hotspur will be defeated by Liverpool but for now we can't be so sure on that.
People make predictions all the time. It doesn't mean they are underestimating the other team. Tottenham is known to be a very inconsistent team. They can win a team like Liverpool and drop points to a team like Everton the next week. People who believe Liverpool will win have a right to believe so because Liverpool has been better and more consistent than Tottenham even though Liverpool's performance has been declining in the last couple of games.
I won't argue about Tottenham Hotspurs inconsistency with winning their games this season especially when they get to meet small team in the league but for big teams like Liverpool ithey can get motivated to do the unimaginable just as they did with Manchester city scoring 4 goals and keeping cleansheet in the game, although anyone may object that City hasn't been in good shape recently but that doesn't change the fact that no one believed Tottenham was going to hammer them 4:0, and that's exactly some kind of scenario that Tottenham might want to try with Liverpool so it's going to be a hard match especially for Liverpool who haven't really been up their sleeves with their form in previous two games.
If you must bet on that game, I suggest you go with over 2.5. I'm sure they score at least 3 goals in the game and I'm also sure of both teams scoring so you can go with that option too, but as for the winner of the match, I can't put my money on any team because anybody can come out victorious. The fact that Liverpool are favourites doesn't necessarily mean they'll win.
You make your predictions about this game sound so sure and that's what I don't like, even though it's possible to happen more than any other predictions like X1 or X2 yet I don't put off the fact that no prediction is sure not until the game's have ended then we know which predictions actually came through.
