I agree with you that this was a very risky strategy. But Madrid is a very experienced team. Ancelotti in particular is a very experienced coach. And he knows the opponent's weakness very well. In this match, Leipzig played attacking strategy from the beginning of the match. They were defeated in the first leg match. So Leipzig needed to win this match by a margin of 2-0. And since Leipzig played attacking strategy, Ancelotti was tactical in this match. He kept Madrid's defense tight. And the Madrid players tried to score from the counter attack. Although Madrid kept their defense tight, they produced several excellent counter attacks. And until the end, Madrid managed to draw 1-1.
This match ended as a draw but Leipzig actually took advantage of this match to show off some of their good young players and they potentially will have some profitable transfers in the summer market.
The way Leipzig's players performed in Real Madrid's home match is absolutely commendable. Leipzig's players really played well in this match, and I would say that Leipzig's players performed better than Madrid's.
However, Real Madrid qualified for the quarter-finals. Performance in Madrid is still very stable. Madrid players are in a good rhythm. Real Madrid will not face any obstacles in winning the La Liga title. Now Ancelotti will try his best for the Champions League title.
