Everton have been told their offer for Sporting Lisbon striker Islam Slimani is “ridiculous”, according to a report.

Portuguese sports newspaper A Bola claim that the Merseyside outfit and West Brom have had approaches for Slimani rejected.

The Express reported Everton had  bid £13.7million bid for the forward last month, while Football Fan Cast claim that Ronald Koeman’s side lodged a higher offer of £17.2million.

A Bola stress that any offer below £25.8million will be considered below Sporting’s asking price for the 28-year-old.

The Blues are looking to bolster their attacking prowess in the current transfer window as the future of their current chief attacking threat Romelu Lukaku remains unclear.

It has been reported that Slimani has missed training sessions at his current club as he may be trying to force a move away from Portugal.

The experienced striker only signed a new contract in Portugal last summer, but it was on the understanding that he would be allowed to leave the club if Sporting received a suitable offer.

Slimani netted 27 goals in 33 appearances in the Portugese top flight last season as his side narrowly lost out on the league title by two points to Benfica.

The 28-year-old boasts an impressive 23 international goals in 43 appearances for his home country, Algeria.

Slimani is under contract with the Portugese giants until 2020, but it is claimed by Portuguese publication Noticias ao Minuto that the striker has a release clause of £24million in that agreement.

The highly rated forward joined Sporting  in 2013 and he has since notched up 56 goals in three seasons.
