Already the match seems to be a very though one for both teams because since Real Madrid have already won the first leg they would just play to secured a draw against Manchester city. But with the recent performance of Manchester city against Newcastle united in the premier league last week I think they might likely secured a win against Real Madrid tonight, because they would going to play the game with full force to win and qualify for the next round.
Why do you equate Newcastle United with Real Madrid in different competitions? It becomes even stranger if you consider the Premier League competition the same as the Champions League competition

. Because if you want to compare the strength of Manchester City this season with its strength last season, I think you will find quite a big difference in the Manchester City team itself. While Real Madrid is still dubbed as the ruler of the Champions League because last season the team also succeeded in becoming champions in the Champions League after slaughtering Dortmund in the final match.
even the Manchester city coach did not see them winning Newcastle united in the fashion it happened which makes it really pointless comparing that game to a champion's league game at the Santiago Bernabeu. it was just one of those good days for Manchester city and they were able to pull up that kind of result against Newcastle.
coming to the Santiago Bernabeu on a one goal deficit is not the best place to be but for a team that is of the capacity of Manchester city, it might just take a goal to turn things around and keep both teams all level and then the tussle for who is able to score more comes fully into light. how trickish this game is one that demands that real Madrid never sit back to assume that a one goal advantage is something too difficult to over tune. if they are able to get another goal first, it is going to be a good way of frustrating Manchester city and that should be the best way of welcoming the premier league champions back to the Santiago Bernabeu.
