The only way Real can go to the next round is that if they win 3-0 or 5-1 or if they get more goals but they only way they can go to extra time is that if the game en end 4-1 Real have the lead. After the first 45 minute (first half) the score was 0-0 but Real had three or four good chances but they couldn't score. When the second half did start Dortmund had two good chances that they missed.
 At minute 83 Real got there first goal but it was too late but five minutes after the first goal Real scored a second goal at minute 88, so Real start trying so hard to get only one more goal that will send them to the final but as i said before it was to late and the game ended 2-0 for real but it was not enough for Real to go to the next round.  

      Today I'm going to talk about the second leg of the game between FC Barcelona Vs. PSG. So after the first leg between the them, the game ended 2-2 the game was at PSG home field.

 FIFA have the rule that who have the most away goals go to the next round  if the two game ended in a draw for example, if the second game end 0-0 or 1-1 Barcelona will go to the next round but if the game end 3-3 or 4-4 etc... PSG will go to the next round. But the only way they can play extra time is that if the score for the second leg game end the same as the first leg game so the game have to end 2-2 .

So the first half of the second leg game ended 0-0 and the two sides play good and they are trying to score a goal that will help them win. The second half started and PSG got a fast first goal was at the 52 minutes so if the game ended at that score PSG would have went to the next round. But what really happened is that Barcelona had to put their best play in even that he have an injury. So he came in the 60 minutes of the second half and he had a big effect on the game because Barcelona score a goal at the 72 minutes and he was the one who assisted the goal.

 The game ended at 1-1 so Barcelona went to the next round of Champions League. The draw in on Friday the 12 of April. The teams that are remaining in Champions League are Real Madrid, Barcelona, Bayern Munich, and Dortmund.
