Yes because Real Madrid's performance is good and because of that they have won a lot of matches and set their standards.They are well liked and people bet on them and this team does not disappoint people.If they play hard and strong, they can beat Dortmund too. However, Real Madrid is strong and will play and win matches against them. Real Madrid also knows this because they are in a good position at the moment. If they lose to him, they will have to lose quite a match. Due to which Real Madrid will suffer a lot, they will definitely win this match.
It's not about playing hard and strong though it contributes but "smartness will still prevail", they have everything to beat Dortmund actually but it seems they aren't on a good stand this season. Last year championship was 2-goals to nil but I don't think they 've ever had it easy playing with Dortmund even though they might have the most win if compared , there was alot of draws on their game and this one might come with a draw or a win.
Thus, determining which team is what seems to be unknown because Realmadrid might actually put on a good performance, Dortmund on the other hand seem to be top on the table which means they cam also surprise Realmadrid with a countering performance or it could be a tie... there's just alot of unpredictable outcomes that might hold for the game
