The agent of defender Vladimir Coufal has hit out at West Ham United this week.
The right-back is considering his future at the club due to a contract standoff with the Hammers.
Per The Sun, he is considering leaving in the summer, as he believes he can earn more elsewhere.
Speaking to Czech site inFotbalu, his agent Karol Kisel said: "Cuf certainly deserves a better salary from the club and a new, improved, longer-term contract for his long-term performances in the West Ham jersey, in addition to the title in the Conference League.
"So far, even after negotiations, West Ham's management sees it differently and has only exercised the option of a one-year extension.
"Cuf is not happy about it as we expected a better offer."
