On April 20, in the 30th round of the Bundesliga, Dortmund sat at home and faced Mainz.

Because the first leg of the Champions League semi-final against Real Madrid is four days later, Klopp has made a large rotation in this league to cope with the Champions League match.

Of course, Klopp, the player who started the game, also asked everyone to give it their all to win this league. Because Bayern Munich has been chasing after them, carelessly.

Mainz really learned from Wolfsburg how to defend to the death, and in this game, he also put on a 532 strikerless extreme stubborn formation, and maintained the score of 0-0 until the 74th minute of the second half, before Cheng Hai rewrote it to 1-0 through a free kick that went straight to the corner.

Although they conceded a goal, it was a league, not a cup, so Mainz did not press out to attack because the score was behind, but continued to defend it.

In the end, Dortmund only won 1-0 in this league, which made many media say after the game: The Hornets are in an offensive predicament.

Compared to the previous games, which often scored four or five goals in one game, Dortmund scored a little too few goals in these two games.

The approach of Wolfsburg and Mainz provides a certain reference for the opponents behind Dortmund.

Even with the dignity of Real Madrid, it has been affected.

On April 23, the first leg of the Champions League semi-final between Bayern Munich and Barcelona was played at the Allianz Arena in Munich.

What no one expected was that after 90 minutes, the score on the big screen turned out to be 4-0: Bayern Munich beat Barcelona by four goals at home, almost killing the suspense of the second leg.

This made Real Madrid coach Jose Mourinho more cautious, and he did not dare to attack the Hornets at the Westphalen Stadium, for fear of a tragedy like Barcelona.

At 20:45 on the evening of April 24, with the referee's whistle, the first leg of the 2012/2013 Champions League semi-finals between Dortmund and Real Madrid officially began at the Westfaren Stadium.

Although Real Madrid did not put on an extreme strikerless formation like Wolfsburg and Mainz, they still focused on defense and put on a 541 defensive counter-attacking formation, and the only striker was Cristiano Ronaldo.

This is the first leg, and it is away again, Mourinho, who was bloodied by Dortmund 13-5 in the group stage, has a shadow in his heart, just want to lose less away from home, and talk about the other second leg.

If you lose a lot in the first leg, go back to your home court in the second leg and go on a rampage. If you don't lose much, or even draw with Dortmund, then the second leg is a different tactic.

Real Madrid's backline is naturally much more luxurious than Wolfsburg and Mainz, and neither the goalkeeper nor the defender can be compared to Wolfsburg and Mainz.

Casillas, Ramos, Pepe, Carvalho, Essien, Khedira, Alonso, Modric and many more, one by one superstars.

In everyone's mind, even if there is one more striker Ronaldo and one less person in defense, it is enough to block Dortmund's attack.

Even many media and fans who have long been tired of seeing Dortmund dominate the football world are already expecting Real Madrid to break Dortmund's goal with counterattacks while blocking Dortmund's attack, win away from home, and return to the home stadium to eliminate Dortmund in the second leg.

However, the trend of the game took everyone by surprise.

Although Real Madrid did protect the penalty area relatively well and did not give Cheng Hai or Lewandowski too many chances, outside the penalty area, Real Madrid gave Dortmund too many free kick opportunities.

Of course, in fact, there are too many to say, and it does not exist, but on the one hand, this is Dortmund's home stadium, and the referee must have a tendency when blowing penalties. On the other hand, it was also because Cheng Hai played too well in today's free kick.

In the previous two games, Cheng Hai also took a few free kicks, but did not score a goal, which gave everyone the illusion that the tactics of Wolfsburg and Mainz were close to success.

As a result, today, Cheng Hai used several desperate free kicks to tell everyone a fact: in the face of Dortmund led by Cheng Hai, it is impossible to hold it just by shrinking and defending.

In the 24th minute, Essinger won the first threatening free kick for Cheng Hai by taking the ball to Gundogan, who broke through with the ball.

Real Madrid's fouls had been on the flanks or in the middle of the field where there was little threat, but this time Essien finally gifted Dortmund a dangerous free-kick.

The ball was about 278 meters away from the goal on the left side of the front of the penalty area, and it was indeed within the range of Cheng Hai's free kick.

Cheng Hai didn't waste this opportunity, and sent the ball directly into Real Madrid's goal with a beautiful powerful arc shot.

Although Casillas reacted to the save at the first time, Cheng Hai's shot was too powerful and the angle was too awkward, and San Cassie still failed to touch the ball after all, so he could only watch the ball go into the net in the air.

1-0！

It was the first time in the last three games that Dortmund had scored a first-half lead, and the entire Westfalen Stadium exploded in an instant, and all the players and fans fell into a frenzy.

Real Madrid's players looked a little ugly, but the Champions League semi-finals were played over two legs, not this one. Therefore, they were not too flustered, and the next game was still the same as before, guarding their own penalty area to avoid giving Cheng Hai a chance.

Cheng Hai did not find a chance to score in the sports battle, and the three-center-back system composed of Ramos, Carvalho, and Pepe blocked the penalty area to death.

Coupled with the assistance of two full-backs, midfielders and others, Cheng Hai and Lewandowski could hardly find any chance to shoot in the penalty area.

And the long-range shot from outside the penalty area, under the interference of Real Madrid's extreme contraction defense and these defenders, plus the goal of Santo Cassi, has not been able to score.

However, although Dortmund's sports attack was blocked, Real Madrid still couldn't do a trickle when defending.

In the 44th minute, when the first half was about to end, Cheng Hai had a delicate dribble at the edge of the penalty area to connect the two, causing panic in the Real Madrid backline.

The third warrior monk Pei Pei, who was about to be broken through by Cheng Hai with the skill of throwing the tail of the ox, looked bad, and subconsciously shoveled Cheng Hai to the ground from the side.

This not only allowed Pepe to receive a yellow card, but also gave Cheng Hai a free kick about 20 meters from the goal on the right side of the arc of the big penalty area.

It's a little close, but it's also a good opportunity.

Casillas also understands that although the ball is a bit close, as long as Cheng Hai stands behind the penalty spot, he will definitely hit the goal directly.

Therefore, Cassie sent the six tallest teammates on the team out and lined up in the wall, hoping to use the advantage of the height of the wall and the problem of too close distance to make Cheng Hai's free kick return in vain.

In Cheng Hai's past free kick penalty history, although free kicks at this distance have also scored, the goal rate is not high.

Casillas hopes this time he won't let himself run into Cheng Hai's doom of scoring in this position and distance.
