The game of football is funny and the result in the game after first half is really a good one for Barcelona team which most people predicted not to win the match because of the absent of their star man Lewandoski. The only shot on target has come from the Barcelona side and they have managed to win 0:1 in the first half I believe they will end up winning the game if Real Madrid do not put much pressure on them. With the performance of Barcelona in the first half they may end up winning the game 1:2 which is the opposite of what you predicted.
The tempo of the match was a bit slow in the second half but indeed there were some very good opportunities considering the current conditions even though both teams still seemed to be cautious.
Now time is almost at the crucial minute, usually Madrid make a little significant movement in the last 15 minutes. Let's hope there are goals scored because it will be a little difficult for Madrid if they push this score to the end.
