Everton are among a host of Premier League clubs targeting Helder Costa.
The winger is currently enjoying a season-long loan with Wolves from Benfica but has attracted interest from several English top-flight sides, including the Blues.
O Jogo claim that Ronald Koeman is set to fight it out with Southampton, West Ham, Middlesbrough, Crystal Palace and Hull City to secure Costa’s services.
It is understood that a fee of £13 million would see Benfica end the Portugal under-23 international’s spell at Molyneux, where he has scored nine times.
Costa, 23, spent the previous season on loan with Monaco and the second half of the 2014/15 campaign at Deportivo La Coruna.
Koeman is keen to add fresh attacking options to his side following Gerard Deulofeu’s departure to AC Milan earlier this week on a half-season loan.
