Last season's third-place finisher, Schalke 04, seems to prefer to do more with less, and apart from spending €4 million to buy out Obasi, who was loaned during last season's winter break, the other key signings are all free transfers.

The arrival of Neustayt, Barnetta and Afele will bring a qualitative boost to the team's midfield and two wings, while the return of Moravec and Diack from loan spells will certainly further consolidate the team's bench depth.

Last season's biggest dark horse, Borussia Mönchengladbach, suffered serious blood loss, and after letting go of Royce, Dante, Neustadt and other key players, Farf needs more time to build a new team.

Losing to Dynamo Kyiv and missing the Champions League group stage, it can be described as a double blow to Borussia Mönchenchen at the economic and competitive levels, and Mönchenchen's reinforcements are actually not small, 12 million euros to buy De Jong, the silver boot winner of the Eredivisie last season, 7 million to introduce Atletico Madrid's future captain Dominguez, 8.5 million to recruit Swiss star Xhaka, and 2.5 million to buy Hoffenheim's German U21 striker Meapa, but the team's integration in terms of tactics and personnel seems to need to be further improved.

Bayer Leverkusen's performance in the transfer market is decent, defender-born Hyypia knows that defense is the first priority, and focuses on the introduction of midfielders, 5 million euros from Real Madrid to buy right-back Carvajal is a highlight, and the **** Scheid poached from Nuremberg is also expected.

In the second echelon of similar standards, Wolfsburg and Hoffenheim have the biggest transfer moves, and Magath, who has always liked to buy in bulk, has also been very busy this summer.

There are also various types of players that Ma Dashuai chooses to bring in, including spending a lot of money (9 million euros) to buy the Eredivisie golden boot Dost, or the Croatian veteran Olic who introduced Bayern for free, and of course, finding good goods such as Messi Pilarge in the Czech Republic (1 million euros).

In order to change the team's previous problem of instability at the back, Magath adopted a combination of old and new. Naldo and Pogaertz can bring more experience to the team, while da Gama's youngster Lemos can bring more energy to the defence.

Babbel's Hoffenheim also completed a lot of big moves, taking the main goalkeeper Stark, Babbel recruited the stronger national Wiese, and it was a free rotation without spending a penny, and the Swiss striker Derdiyok who bought Leverkusen for 5.5 million euros can be described as killing two birds with one stone. It not only strengthens the team's forward line, but also weakens the opponents who are competing for a European place.

In addition, the 6 million euro purchase of Real Madrid's young center forward Joselu, who is regarded as Llorente II, is expected to greatly improve the team's aerial combat strength, as for the signing of Stuttgart's French central defender Delpierre and Wolfsburg Brazilian central defender Chris to effectively consolidate the defense, as well as the loan of Japanese star Takashi Usami and the return of Argentine defender Zucurini after the loan period will bring more tactical options to the team's midfield.

Bremen have also completed a major change, with the likes of Petersen, Elia, De Laubné and Gebreselassie bringing a new look to the Green Parrots. Stuttgart has not been well on the way in terms of recruitment, and the biggest gain can only be the loan of defender Hoagland from Schalke 04.

And how could Dortmund not strengthen the reinforcements! Faced with the frenzied recruitment of all the teams in the Bundesliga, Klopp also struggled to sit still. Fortunately, Klopp has been prepared, first of all, 5.5 million euros from Stuttgart to bring in Shieber as a substitute for Lewandowski, after all, Barrios has left Dortmund to join Guangzhou Evergrande.

Kirsch was brought in from Kaiser Old to be the team's backup defender, after all, Subotich's total injury last season made Klopp very worried, these are just ordinary players, and Reuss, who has been signed before, will also come to Dortmund this season to play.

Dortmund is not willing to lose the Champions League again this season, and is also determined to increase investment. Therefore, Dortmund President Watzke gave Klopp a transfer fee of 20 million euros in order to strengthen the team. Klopp has only spent 6 million euros on this money so far, and there are nearly 15 million euros left unspent.

This time Klopp's target is Musa Sissoko, the 22-year-old who plays as a midfielder, and the 1.87m tall is fierce in defence, extremely versatile and has a good long-range shot. He joined the youth academy of Ligue 1 rivals Toulouse in 2003 at the age of 14 and in the 07-08 season, Moussa Sissoko rose to the first team and developed into an absolute mainstay, making 183 appearances for the team in Ligue 1, scoring 21 goals.

On the national team's side. Moussa Sissoko has been a key member of France's youth team at all levels since 2005, he was first promoted to the senior team in 2009 by then-France coach Domenech, and on October 6 of the same year, Moussa Sissoko made his international debut in France's World Cup qualifiers against the Faroe Islands in South Africa.

Mousassissoko plays as a midfielder, often plays as a midfielder and winger, and has a very good foot work, steady ball control, delicate and precise passing, and extremely fast, reminiscent of the young Vieira.

This season, Kloll is in his thirties, and Kyle's physical strength is difficult to be a starter, so Klopp has always wanted to buy a physical midfielder, and Bender is also more prone to injury, so Klopp has taken a fancy to this French midfielder with excellent physical fitness and good ball passing, the main reason is that Musasisoko is cheap, and Dortmund only spent three million euros to bring Musasisoko to Dortmund, You must know that Sissoko will also join Newcastle for 2.5 million euros in the near future, so it is really worth buying this player at this time.

The other is the centre-back position, and although Subotic has performed well, Klopp still hopes that he can bring in a young and capable centre-back to form the Dortmund backline with Hummels.

Klopp chose to buy Papastathopoulos this time, Papastathopoulos was born in 1988, known as "Brother Bird" and "Brother Peach Stealer" (named after JJ who caught Messi in the World Cup Greece vs Argentina match in South Africa), with a balanced ability on the left and right feet, especially the two wingbacks on the left and right are the most commendable.

He was selected for the Greek national team in 2008 and was immediately selected in the 24-man squad for Euro 08, but was excluded from the 23-man squad by coach Rehhagel at the last moment, but the South African World Cup was trusted by Rehhagel, who started against Argentina and Nigeria, and his performance was also recognized by the coach and fans.

In 2005, Papastathopoulos transferred from Apollo to Greek giants AEK Athens for 300,000 euros, and after three seasons of forging, Serie A team Genaia recruited him for 3.8 million euros, and in the 09-10 season, Papastathopoulos played 33 games for the team, including 27 starts and one assist.
