Manchester Evening News: The former Spanish goal is back in top form, and Pep Guardiola wants to recruit the champion.

The Telegraph: With an hour to go in the winter window, Arsenal manager Arsene Wenger and others are at Heathrow Airport, do Arsenal want to bring in a star at the last minute?

London Evening Banner: In the just-concluded 23rd round of the Premier League, Arsenal lost to the Hornets at home, and dropped the chain at a critical moment. With two goals conceded in four minutes in the first half and a five-game winning streak at home ended, the Gunners are getting further and further away from the top of the table, with Cazorla's absence making it difficult for the Gunners to function in midfield, and Arsenal will need to find a replacement for the Spaniard if they are to compete for the Premier League title this season.

……

Manchester City coach Josep Guardiola personally went out to meet Zhang Zhetian, which attracted the attention of many media and teams, but the meeting time was very short, so they did not know where Guardiola went and who he met.

And according to Manchester City's record and lineup, the media and experts analyze that Guardiola may have to change the goalkeeper.

In this world where the Internet is extremely developed, there is no impermeable wall, and Guardiola's flight to Portugal caused Arsenal manager Arsène Wenger and others to be nervous.

Fortunately, in the following days, there was no official movement from Manchester City, and Guardiola attended the pre-match press conference for Wednesday's away game against West Ham on the afternoon of January 31, at which Guardiola made it clear that he would not buy people in the winter window, which decided that Zhang Zhetian would either remain at the University of Coimbra, or Arsenal boldly accepted Zhang Zhetian's conditions.

On January 28, the University of Coimbra narrowly defeated Pennafell 3-2 at home, although they conceded two goals, but in the last few minutes, the University of Coimbra was sent off two people one after another, and at the last moment, Zhang Zhetian saved Pennafell's close-range header with a pair of big palms, kept the three points, and continued to maintain the third position in the league with a one-point advantage.

Although he conceded two goals in this game, he still won the Player of the Match award again with a decisive save at the last moment.

So far, Zhang Zhetian has made 27 appearances for the University of Coimbra, with a total of 2,430 minutes (calculated as 90 minutes), including 24 games in the Portuguese League and 3 games in the Portuguese Cup, with 13 wins, 8 draws and 6 losses, scoring 28 goals and conceding 18 goals, with an average of 0.67 goals conceded per game.

Generally speaking, the statistical evaluation of goalkeepers is generally based on the success rate of saves and the average number of goals conceded per game.

However, the former cannot truly fit the intuitive feeling of experts and fans, and sometimes there will be "exceptions" where the success rate of excellent goalkeepers is relatively low and the success rate of ordinary goalkeepers is very high, because some shots may be easier to save, while others must rely on "divine save" to save.

The latter is closely related to the overall strength and tactical play of the team, the goalkeeper of the team that concedes fewer goals usually performs well, but the goalkeeper of the team that concedes more goals is not necessarily not good.

In order to make the evaluation more fair and impartial, an ExpG2 value based on the goal expectation model has emerged.

ExpG2 is simply the expected goal value, which includes a comprehensive consideration of the position of the shot, the footwork of the shot, the trajectory of the shot, and the trickiness of the shot.

The ExpG2 rate is equal to ExpG2 divided by the actual number of goals conceded, and the higher the value, the higher the probability that the goalkeeper will save the dangerous ball.

The same goal conceded, missing a simple shot or a mistake to lose a point, compared to a single goal or a dead end world wave, is the same in terms of save success rate, but the ExpG2 rate is far from the same.

Up to now, Zhang Zhetian has made 27 appearances and 14 clean sheets, contributing an average of 13.8 saves per game, with a save success rate of 89%, an average of 8.5 points per game in the league, an average of 9.6 points per game in the 3 Portuguese Cups, and an ExpG2 value of 1.19, which is not only the first goalkeeper in the Portuguese League, but also the first goalkeeper in the Portuguese Super League, surpassing Porto's main goalkeeper, Spanish front goalkeeper Igor Casillas.

With a whopping 998 passes, an average of 35.64 passes per game, and a 96% pass success rate, it is no wonder that Guardiola regards Zhang Zhetian as a goalkeeper who fits his tactical system.

However, the young Zhang Zhetian also has a shortcoming, that is, mistakes. Of the 18 goals conceded, except for half of them were teammates, the rest were conceded due to mistakes.

However, I believe that with the accumulation of Zhang Zhetian's game experience, as long as he can have a stable opportunity to play, Zhang Zhetian believes that he will grow better.

Becoming the second goalkeeper to win the Ballon d'Or after former Soviet Union goalkeeper Lev Yashin is one of the small goals of Zhangzhetian.

"Palm, I wish you success in the Premier League." Francisco Costinha reluctantly bid farewell to Zhang Zhetian who was carrying a duffel bag.

The liquidated damages of 2 million euros are simply equivalent to giving away in front of many big teams, and the senior management of the University of Coimbra regrets it very much, knowing that this Chinese teenager is so powerful, and the liquidated damages should be added to the 0.

But for Costinha, if he can, he simply does not agree to sell Zhang Zhetian, as long as the University of Coimbra adapts to the Portuguese Liga this season, with Zhang Zhetian, he will definitely be promoted to the Portuguese Super League next season.

All of this was ruined by the incompetent club management.

On the evening of January 31, Arsenal lost to Watford at home, falling to third, and the gap with Chelsea at the top of the table widened to 9 points, and Liverpool and Manchester City behind 2-5 points, and the next league game is about to go to Stamford Bridge against the hot Chelsea.

If Arsenal loses in this crucial battle, not only will they have no hope of winning the title this season, but it is difficult to say whether they can keep the top four.

Moreover, Gunners coach Arsene Wenger is still suspended and cannot enter the coach's box, and the loss to the team has been highlighted in the loss to the Hornets.

With an hour left to close the transfer window, the FA received a transfer profile.

At 23:59 p.m. London time on January 31, the Arsenal office received a fax, and then, there was a cheer.

January 31 is the fourth day of the Lunar New Year in China, and it is the day for the Chinese people to welcome God.

On this day, the Premier League giants Arsenal also ushered in a god, a door god from China.

"Welcome to London, Palm." Wenger's smiling hands clenched the giant palm of the palm.

More than 300 kilometers away in the city of Manchester, Guardiola sighed softly, and suddenly, a smile appeared on the corner of his mouth, looking in the direction of London.

Palm, you're going to snipe Antonio for us, right?
