If the city of Burnley is impregnable, to break it, you must have a ram.

Many reporters and Gunners fans have criticized Arsène Wenger's sluggishness in making substitutions, but this game showed them a fake Wenger.

Before the start of the second half, Arsenal used up three places in one go, showing their determination to open the red wine bottle and drink the wine.

No.10 Jack Wilshere replaces Alex Iwobi, No.12 Oliver Giroud replaces Nacho Monreal and No.23 Danny Welbeck replaces Alexandre Lacazette.

It was clear that Lacazette, who lacked the ability to strike from the air, was not fit to break the bus, and this time he was replaced by a tactical need, although Lacazette was unhappy in his heart.

The reason for the change for Iwobi is simple, the Nigernian youngster lacks the ability to pass through the ball and does not do a good job of linking up Aaron Ramsey and Alex Sanchez.

As for Monreal's departure, in addition to the opponent's only one striker and a waste of resources by placing three central defenders, it is also to change the formation to a back four, and the young, strong and more impactful Sejad Kolasinac is more suitable to play left-back in this game.

Wilshere came out with Ramsey and Tan Xibi to form a three-man midfield, and 3421 was changed to 433.

It's 433 rather than 217, with Héctor Bellerin and Sejad Kolasinac playing as wingers, Welbeck and Giroud squeezing the opposition defence into the box, Alexis Sanchez roaming freely on both flanks, Wilshere and Ramsey roaming around the edge of the box, and Arsenal devoting a full seven men up front against Burnley's eight and a half defences.

Why do you say eight and a half?

Don't look at John Gudmundsson's position as a right midfielder, his main position is actually a right winger, but also a backfoot winger, because his main foot is left-footed.

Gudmundsson, who had spent a year in the youth teams of Chelsea and Fulham, went to the then Eredivisie champion AZ Alkmaar to exercise after making a name for himself in Iceland, don't look at his height of 1.86 meters, speed and breakthrough are the biggest magic weapons, and many wingers like to cross differently, Gudmundsson chooses more 45-degree angles to find the back point.

During his time at AZ Alkmaar, Gudmundsson, who switched to right winger, was touted as the "Icelandic Robben" by the local media for his outstanding performances, but his in-cut shot basically hit the high platform, a nickname that is nothing short of a hit?

The shortcomings of Iceland's flying wings are obvious, the ball is quotient, the style of play lacks change, the ball is always a tendon, as a winger rarely changes positions, the physical fitness is average, it is easy to be looked at by the opponent to death, and it is difficult to get rid of it once it is marked.

During Burnley's three-game winning streak, Gudmundsson, as the main right midfielder, not only played the whole game, but also contributed two assists, Sean Dyche reused him because of his speed and crossing ability on the wing, but this game met Bosnian tanks, coupled with Arsenal's suppression on the field, Gudmundsson could only help defend in the backfield, and several breakthroughs with the ball were destroyed by Kolasinac, obviously the two are not on the same level.

Thanks to the help of right-back Matthew Lowton and Gudmundsson's strong execution, Burnley's right side was no problem for the time being, but the Icelanders, who were never strong in defence, exposed their defensive shortcomings after Arsenal stormed the left in the second half.

In the 49th minute, Sanchez broke through Gudmundsson's defense and hit Burnley's penalty ribs, Lowton recycled the middle, Sanchez changed to cut inside the penalty area line and then suddenly shot with his feet, although the ball was high, but it also scared the Burnley players into a cold sweat.

In the 52nd minute, Kolasinac and Sanchez both encircled Gudmundsson, Kolasinac cut off the ball and passed to Tan Xibi, Tan Xibi directly did not stop the ball and passed to Bellerin on the right side, Bellerin did not hesitate to grab the front 45 degree angle cross to the back point on the opponent, Giroud struggled for the top, and was pushed out of the bottom line by James Tarkovski.

Despite failing to score, Arsenal's attacking threat was much greater than in the first half, especially with Wilshere's dribbling and Ramsey's movement putting more and more pressure on Burnley's defence.

Especially on the right side of Burnley, Gudmundsson was clearly targeted by Arsenal, and Dyche made a decisive adjustment, replacing the Icelander with No. 18 Ashley Westwood at the back to strengthen the defense of the ribs of the penalty area.

I have to say that Dyche has a hand in the bus, and the defensive intensity of the top three in the Premier League makes Burnley unable to attack in front of the Premier League giants and protect themselves.

After Wilshere came on the pitch, Arsenal's midfield ran more, on the one hand, to pull out space, and on the other hand, to open up a long-range cannon for Tan Xibi.

In the 55th minute, Bellerin's cross was cleared by Burnley captain Benjamin Rice's header.

In the 58th minute, Kolasinac crossed, and Welbeck managed to grab the spot, but set the ball high.

A minute later, Tan Xibi cut off the ball of Steve DeVell, Robbie Brady and Jeff Hendrick in succession, receiving applause and cheers from the Arsenal fans in the stands, Dyche on the sidelines frowned and shook his head, turned to the assistant coach, and spread his hands helplessly: "It's hard for us to make trouble for Arsenal's defense, that No. 28 is simply a wall!" ”

The assistant coach comforted him with a wry smile: "Even Messi can't pass him, it's normal that our players are not his opponents." ”

"You still have to be careful with your long-range shots," Dyche said worriedly, "and we can't relax our attention for a moment, and if we are the slightest careless, we will fall short." ”

Thinking of Tan Xibi's five world-wave long-range shots against Everton, Manchester City and Tottenham, Dyche felt his bald head tingle.

"The effect of high-altitude strikes does not seem to be very good." Steve Boulder told Arsene Wenger: "Dyche seems to have learned the lessons of the game against Manchester City and worked on defensive headers. ”

Seeing Giroud and Welbeck fighting each other in the box, with a low success rate for headers, Wenger nodded to Boulder and said: "We're still not very good at playing high balls, Jack, Alex they have to run more and create space. ”

After saying that, Wenger came to the sidelines and called Schkoderan Mustafi, who was closer to him: "Reduce the high-ball attack, run more aggressively, pass the ball as straight as possible, don't be afraid of mistakes, our current defense is not afraid of them counterattacking." ”

Mustafi nodded and returned to the pitch to relay Wenger's instructions.

In the 65th minute, Burnley made another substitution, No. 26 Phil Bardesley replaced the yellow carded De Vell, and No. 11 Chris Wood replaced Ashley Barnes.

"Alex, Alex!" Taking advantage of Burnley's substitution, Tan Xibi pulled Sanchez and whispered to him.
