Everton face a battle to keep hold of young winger David Henen.
The teenage Belgian is currently impressing on-loan at Fleetwood Town.
O Jogo says scouts from Sporting CP and Napoli have been posted to Fleetwood games to see Henen in action.
The midfielder signed permanently for Everton last summer, committing himself to a deal to 2018.
Everton boss Roberto Martinez regards the 19 year-old highly and will be reluctant to lose the youngster.
