Chelsea face a demand from Fiorentina for payment after former loanee Mohamed Salah returned to Stamford Bridge last week.
The Serie A outfit agreed in January that a €1m fee would extend Salah’s loan deal by another season with an option to buy in 2016 in a deal worth another €18m.
However, the former Basel star rejected a return to Florence earlier this month but the club insist that he missed the deadline to veto the move.
As a result, a war broke out between the two with the Viola threatening legal action against the Egyptian international, while Chelsea have now been dragged into the situation too.
According to Sport Mediaset, as reported by Football Italia, Fiorentina have given up on getting Salah back but they want to be compensated for losing him after seemingly having an agreement.
It is reported that they have asked for the €1m back plus another €3m which they believe they deserve after developing the player as he scored nine goals in all competitions for Fiorentina last season after struggling in his first few months in the Premier League.
