Andre Silva says he has a "clear conscience" amid claims by Sevilla coach Joaquin Caparros that he has exaggerated his injury problems.
Silva, who is on loan from AC Milan, has not played for the club since April 4 but could be called up to Portugal's squad for their Nations League Finals campaign in early June.
That has sparked outrage from Caparros, who has questioned the severity of Silva's knee injury and has even gone as far as to suggest that UEFA should intervene if Portugal do attempt to call him up.
