All Real Madrid fans will also hope the same as you, unless they want to win bets against their own team to get bigger profits such as betting on Napoli or a draw. Of course, this is a normal thing in the world of gambling considering that someone doesn't always have to stick with the favorite team to win the bet, but sometimes being on a different path can also give them luck.
I'm sure Real Madrid won't make any mistakes against Napoli today. Honestly, this is a tough match for Real Madrid considering that this team lacks a striker, but with Vinicius there, I am optimistic that their attacking power will be very strong throughout the match. I definitely don't expect a defeat for Real Madrid, but things don't always go as we expect.
What you said here applies to me as well, as a fan of Real Madrid and also placed a small bet today for them to win this game since sportsbook has some good odds for us. I won’t say that I’m sure about their victory against Napoli but Real Madrid always been doing better in important events than what they perform elsewhere and other matches. Beside that, in all the previous seasons for them in UCL they always either they end it by winning the trophy or at least perform well.
However, I don’t take off the possibility of Napoli winning today, as they are playing at their own house so they have an advantage but Real Madrid even in LaLiga they were definitely performing better playing away than when they play home. It’s only few minutes before the start of the match so let’s keep an eye here and there. It’s a good match to enjoy after all.
