Liverpool and Barcelona agreed a unique clause during transfer negotiations for Philippe Coutinho in January 2018, which can cause trouble for Gini Wijnaldum's Barcelona swoop.
Newly appointed Blaugrana manager Ronald Koeman wants to work with his former midfield general once again and bring him to Catalonia as part of his new Barcelona project. Wijnaldum's Anfield future remains up in the air with Liverpool still yet to agree a contract extension with his entourage.
There has been some suggestion that the Reds could look to move the Dutchman on to fund a swoop for Thiago Alcantara, who is available for £25million. However, Liverpool would need to break their own agreement over transfers with Barcelona if they were willing to let Wijnaldum join the Catalan giants.
According to the
Daily Mail, back in January 2018 during talks for Philippe Coutinho, Michael Edwards seized initiate and negotiated a clause with Barcelona which meant they were unable to sign any Liverpool players until 2021.
Should Barcelona which to break this pact, they would have to pay a £90m premium on top of any potential transfer fee. The agreement was brokered by the Reds to prevent their counterparts from launching another lucrative swoop for the likes of Mohamed Salah and Sadio Mane.
If Barcelona make a formal approach for Wijnaldum, Liverpool have the option to put the agreement to one side.
