BBC: Drapp s injury triggers a chain reaction of & affects 9 people, Bayern rents Jackson to bear the brunt

The summer window deadline was due to Drapp's accidental injury. The BBC analyzed this: Drapp's accidental injury not only affected Chelsea, but also triggered a series of chain reactions in the European transfer market.

Bayern Munich was hit first - Chelsea withdrew its permit on Saturday afternoon and refused to allow its striker Nicholas Jackson to undergo a medical examination. After a 2-0 victory over Fulham, the Blues contacted Portugal Sports and forward Conrad Hader's team at the same time.

The two clubs have since started a game: Chelsea asked Bayern to propose a permanent transfer offer to raise funds to buy Hader. Bayern's offer to Atlanta for alternative options Ademora Lukeman was also rejected.

Hader finally chose to join Red Bull Leipzig for his commitment to a more important lineup role. Meanwhile, Chelsea's loan club Sunderland started negotiations to recall Mark Gillou, when Jackson was stranded at the hotel in Munich all night.

Sunderland reluctantly agreed to release the 19-year-old young player and was then forced to turn to Brian Broby, who was seeking Ajax. This means Ajax needs to find a replacement, and they quickly signed the Celtic target Casper Dorbery from Anderlecht.

The Celtics, who missed Dolberg, urgently looked for multiple forward options at the night of closing the window, almost reaching a deal with Chelsea's David Datro Fofane to form a complete closed loop. Fofaner rejected the Celtics and chose to join Charlton (but the deal eventually failed), prompting the Celtics to contact Isinacho, who terminated the contract with Sevilla.

Originally, Chelsea planned to pass the final stage of the transfer window smoothly through the "sell only, but not buy". But Delapp's injury on Saturday put the Blues in panic - just hours before the game, AC Milan just signed French striker Christopher Nkunku, and Chelsea had allowed Jackson to go to Munich for a physical examination.

With the severity of Drapp's injury clear, Chelsea unilaterally suspended the deal with Bayern, which aroused strong dissatisfaction among Jackson and his team. Chelsea evaluated the feasibility of signing Hader without a offer, and the plan to recall Jiwu, and finally chose to let Jackson return.

Recalling Jiwu proved to be the most feasible option, which avoided the trickiest option to force Jackson to return against his will. Chelsea ultimately believed that Jiwu was a better solution: he had the Premier League experience that Hader lacked, was familiar with the tactical system and had the characteristics of success.

Sources revealed that Chelsea finally won better conditions for Jackson: Bayern will pay a loan fee of 14.3 million pounds and trigger a forced buyout clause based on the number of appearances. The return of over £70 million is worth the price of the player who bought from Villarreal in 2023.

It is worth mentioning that before this incident, Chelsea had tentatively offered 34.7 million pounds to buy Barcelona attacker Fermin Lopez.
