Real Madrid's home ground will be a tough one for Manchester City to beat Real Madrid. However, if they continue to play like we have seen in their current performance, then their match against Manchester City could be very challenging. In that case, if Real Madrid can maintain their dominance in today's match and can utilize their strong performance, then victory is definitely possible, moreover, since they are one goal ahead. So Real Madrid can feel a lot of advantage here, moreover, they will also have a lot of advantage in their home ground, in that case, if they attack strongly, it will be possible to beat Manchester City today as well. If Real Madrid can win today's match, then they will qualify for the next match, in that case, Real Madrid must play today's match with their best performance.
You also have to admit that just as it might be difficult for Manchester City to win this match, it might also be a very difficult task for Real Madrid to win. But it's true that this match is going to be much more difficult. In a previous match, we must have seen that Manchester City tried to fight Real Madrid very well, so maybe in today's match they will have that conviction. Moreover in my opinion the chances of winning this match today are the most likely for Real Madrid since they have done and won a remarkable performance in the previous match. In this match the most convenient thing for Real Madrid will be that they will play in their home ground.
You are absolutely correct, one team winning the match is really going to be hard and Real Madrid is or will be very careful because they have 1 goal so even if they draw it doesn't matter and this is the more reason why Manchester city will fight to their last breath tonight because they really need to win in order to qualify and for them to qualify they will have to win with 2 goals margin since Real Madrid already have 1 else they will go for extra time but Real Madrid experience in the champions league is what I don't really understand.
