Everton manager Ronald Koeman admits the improvements Romelu Lukaku has made to his game this season have only made him more attractive to other clubs.
Koeman believes the Belgium international is a better all-round player this season, irrespective of the 24 goals which have made him the Premier League's top scorer.
Lukaku, who has told the club he will not sign a new contract to replace the existing two years on his current deal, is already six better than last year's top-flight total and while that has helped Everton secure Europa League football it has made him even more of a target for potential suitors.
