Club Brugge defender Stefano Denswil is being watched by Everton.
Denswil, 23, is also on the radar of Monaco and AC Milan, who watched him in Champions League action against Porto this week.
But Everton scouts were also at the game to run the rule over the former Holland Under 21 international, who could cost £10m, says the Daily Star.
Denswil, who came through the Ajax youth system and went on to win two league championships with the club, is most comfortable as a left-sided centre back.
