Bundesliga Daily Report - 2026-09-02

Borussia Dortmund signed Arsenal midfielder Ethan Nwaneri on a season-long loan for the 2026-27 campaign, completing the move shortly before the transfer window closed. The 19-year-old joined after Dortmund lost summer arrival Giannis Konstantelias to a serious knee injury in the club’s opening game against Hamburg. The agreement was reportedly worth around £4 million, with Dortmund covering Nwaneri’s wages. Arsenal also retained an option to recall him in January, according to football.london. Nwaneri spent the second half of last season on loan at Marseille and now moves to the Bundesliga for another spell of senior football.

Dortmund sporting director Lars Ricken described Nwaneri as technically gifted and said the club had needed to strengthen its squad in the wake of Konstantelias’ extended absence. The teenager has made 51 professional appearances for Arsenal, scoring 10 goals, and became the Premier League’s youngest player in September 2022. Dortmund’s move gives him a second consecutive season away from north London, while Arsenal retain control over his longer-term development. His ability to operate in attacking midfield and across the forward line offers Dortmund additional flexibility during a campaign disrupted by the loss of Konstantelias.

Bayer Leverkusen brought Moussa Diaby back to the Bundesliga from Saudi champions Al-Ittihad, with the France international signing a contract through June 2031. The transfer was completed on Tuesday after prolonged negotiations and final approval from Al-Ittihad. Diaby, 27, previously spent four seasons at Leverkusen after joining from Paris Saint-Germain in 2019, developing into a France international before leaving the club three years ago. He will wear the number 19 shirt again, returning to the side where he established himself as one of European football’s most dangerous wide players.

Leverkusen sporting managing director Simon Rolfes said Diaby’s pace and one-on-one ability would broaden the team’s attacking options. Rolfes also praised the winger’s attitude and described his qualities as an addition to the club’s attacking game. The return gives Leverkusen a familiar attacking threat and reunites the player with the Bundesliga club where he previously made significant progress. A contract running until 2031 represents a substantial long-term commitment, while Diaby’s experience in Germany should help him settle quickly after his spell in Saudi Arabia.

Schalke signed South Korea forward Hwang Hee-chan from Wolverhampton Wanderers on a season-long loan, completing the deal just hours before Tuesday’s transfer deadline. The move runs until June 30, 2027, according to the German club, while German media reported that Schalke have an option to make the transfer permanent for €3 million. Hwang, 30, returns to Germany after five seasons in England and previously played for Hamburger SV and RB Leipzig between 2018 and 2022. His move followed Wolves’ relegation to the Championship and a decline in his involvement after he scored 12 Premier League goals in 2023-24.

Schalke have returned to the Bundesliga after four seasons in the second tier, winning the 2. Bundesliga title last season. The club’s announcement came so late that it was issued without a photograph of Hwang wearing Schalke colours. He is targeting a debut against Bayern Munich on Saturday, which would immediately place the forward in one of the league’s highest-profile fixtures. The loan gives Hwang a chance to rebuild his momentum in a familiar country, while Schalke have secured an experienced international forward with a relatively modest purchase option.

Hamburger SV completed the permanent signing of Fabio Vieira from Arsenal, according to Sports Mole. The Portuguese midfielder had spent the 2025-26 season on loan before making his move to the Bundesliga club permanent. Vieira leaves Arsenal after a spell in which his most notable contribution came through a trophy-winning penalty, although the report did not state the final transfer fee or the length of his Hamburg contract. The deal was confirmed during a busy transfer period for Arsenal, who were also reported to be completing several other departures.

Vieira’s move gives Hamburg a midfielder with Premier League experience as they establish themselves back in Germany’s top flight. Arsenal have continued to reshape their squad after winning the previous season’s domestic title, and a permanent departure removes one player from a crowded midfield picture. For Hamburg, retaining a player already familiar with the club should reduce the adjustment period compared with a new arrival. His technical qualities and previous season in Germany now give him an opportunity to make a sustained contribution rather than return to north London after another temporary spell.

Hamburg signed Wolverhampton Wanderers left-back David Moller Wolfe on loan on deadline day, with the agreement including an option to buy if the Norwegian impresses in Germany. The 24-year-old had made only 11 Premier League starts for Wolves last season and had collected 156 minutes across three appearances under manager Cesar Peixoto this term. The move offers Wolfe another opportunity to play regularly in a top division. Hamburg’s next fixture is Sunday’s meeting with Mainz, which could provide his first chance to appear in the club’s colours.

Hamburg sporting director Claus Costa said Wolfe’s dynamism, defensive assurance and style of play made him an ideal fit. Costa highlighted the full-back’s physicality, athleticism, energetic running and high-intensity approach as qualities that would give the squad additional options. The loan reflects Wolfe’s need for a more consistent role after limited involvement at Wolves, while the purchase option gives Hamburg a route to retain him if the arrangement works. His arrival strengthens competition at left-back and provides the promoted club with another physically demanding option.

Hamburg defender Daniel Elfadli joined Austrian double winners LASK on loan, completing his move before the deadline to register players for the Champions League. According to Bild, the 29-year-old turned down an offer from SV Elversberg on deadline day. The deal reportedly contains no option to buy, leaving Elfadli under Hamburg contract until 2028. He joined HSV from 1. FC Magdeburg two years ago for a reported €800,000 and played a key role during the club’s promotion campaign before losing his starting place in the second half of last season.

The move offers Elfadli the prospect of continental football with LASK, who have qualified for the Champions League and are due to face Real Madrid and Liverpool. Hamburg’s defensive hierarchy changed after promotion, with Sebastiaan Bornauw arriving as a new leader and youngster Shafiq Nandja moving up the pecking order after Luka Vuskovic’s departure. Elfadli’s loan therefore creates a path to regular football while preserving his link with Hamburg. For LASK, it adds experienced Bundesliga-level defensive cover without committing to a permanent transfer.
