Everton enjoyed the services of Chelsea centre-back Kurt Zouma during a season-long loan at Goodison Park last season.
The France international has since returned to Stamford Bridge where he is looking to convince manager Frank Lampard that he deserves to be in his first-team next season.
While Toffees’ boss Marco Silva is still not giving up on having Zouma back on Merseyside, there is little time left in the summer transfer window and he must act quickly.
Should Everton fail in their pursuit of the Frenchman, there is another quality centre-back they could bring back to the club, though.
