Everton are believed to be the latest Premier League club to be showing interest in Sporting Lisbon striker Islam Slimani.

The Daily Mail is reporting Manchester United, Liverpool and West Ham United all sent scouts to watch the Algerian in action in Sporting's 3-1 win over Pacos Ferreira on Saturday, while Crystal Palace and Sunderland have also been keeping tabs on Slimani.

Roberto Martinez's Everton reportedly made enquiries about the 27-year-old over the weekend.

Slimani, who has scored eight goals in his last five games, is understood to have a £22.5million buyout clause in his current contract with Portuguese giants Sporting.
