Everton face stiff competition for Dinamo Zagreb prospect Ante Coric.
Blues boss Roberto Martinez has made enquiries for the midfielder, who had tests with Chelsea as a junior.
However, Sportske Novosti says PSG had scouts posted to see Coric in action against Hajduk Split for last week's 1-1 draw.
Coric is well aware of the growing interest in his signing, but is happy where he is.
The midfielder's family and agents believe his career would be best served with another year with Dinamo.
