Real Madrid don't have good memories against Manchester City from the time they last met up. 
At Etihad they got a really huge defeat like 4-0. Considering the way Real Madrid have been playing in the Champions League recently I can't be very positive about them. The performance against Leipzig was just horrible. If Leipzig were a more capable team they would be the side to advance.
Ancelotti should prepare his players strongly for this round. I don't think they would lose home in the first leg but the second leg will be way tougher.
The way Real Madrid players are performing this season I'm not sure they are ready to get the Champions league title this season. The champions league will be tough for Real madrid because the players are not putting efforts in their games. I think because of how Real Madrid are not very strong this season their main concentration is to get laliga title and right now they are leading laliga. From the performance of Real madrid this season it looks as getting the Champions league won't be easy for them. At Etihad they got a really huge defeat like 4-0.

Man City's performance is not as good as last season, but they are still a difficult opponent for Real Madrid and I think it is quite difficult to predict who will qualify for the final round. Real Madrid itself also does not have an impressive performance this season. Several times they lost unexpectedly against small teams that they should have easily beaten, it's just that they are quite lucky, because Barcelona also has inconsistent performance. Meanwhile, Man City apparently has quite a dependency on Kevin De Bryune. So because from the start of the season De Bryune couldn't play due to his injury, therefore Man City couldn't play as well as last season.
