I don't doubt Man City but I always hope that Real Madrid can take revenge for last season's defeat.
This is a very difficult target, Madrid does have quality players and is ready to face Man City in better conditions. However, the problem is Pep Guardiola strategy often makes things difficult for Ancelotti. Ancelotti is a coach who has experience in the UCL, no doubt about him, but if he can't find the weakness in Guardiola's strategy, when you say that Madrid can win with a big score, I'm not sure about that. Even a 2-0 win is very difficult to achieve. IMO
It's going to be a tight game for both teams, they both have the qualities to progress to the next stage but in this case one team has to progress which has to be the best team over the both legs, the first leg at the Santiago Bernabeu on Tuesday might go in favour of Real Madrid because if the home advantage,the teams will take full advantage of their respective home grounds with the motivation from the fans, Madrid this season has been exceptional as they top their league with a good number of points, but the Same can't be said about Manchester city who are third on the premier league and most take every league match seriously if they are to stand a chance to defend the trophy they won last season,
Talking about The two coaches Carlo Ancelotti and Pep Guardiola their head to head record in the knockout stage of the champions league says it all , as Carlos Ancelotti has the upper hand, they are both experienced coaches but I will give it to Madrid based on the present form of the teams ,
and not to forget Real Madrid are the kings of Europe they just know how to create something out of nothing.
