Liverpool allowed Marko Grujić to join FC Porto on a season-long loan deal earlier this week.
The midfielder spent the last two seasons on loan at Hertha Berlin and they retained an interest in bringing him back to the club.
Hertha wanted a loan deal, but the Reds were looking to sell the 24-year-old on a permanent transfer.
Werder Bremen were then linked with the Serbia international, but a potential loan move to the German club collapsed on the deadline day, and Bild earlier suggested the salary structure was the reason behind it.
This week’s edition of SportBild looks into why deals Werder couldn’t complete, including the sale of Milot Rashica and the loan signing of the Liverpool owned player.
The deal for Grujić failed because ‘the cash register [of Werder Bremen] is empty’.
Davy Klaassen’s sale to Ajax helped the German side earn €11m, but the money was used to exercise the purchase obligation for Ömer Toprak and Leo Bittencourt.
Werder Bremen’s financial situation would have improved if they had managed to sell Rashica.
Unfortunately they didn’t, and Grujić ended up joining Porto on a season-long loan deal.
