Manchester United's formal interest in Marouane Fellaini has reportedly prompted Everton to identify replacements for the Belgian, with Juventus midfielder Luca Marrone the top target for Roberto Martinez.
According to the Daily Star, Everton are scouring the market for reinforcements with Fellaini's future uncertain, and have marked out 23-year-old Marrone as a potential acquisition.
The former Italy under-21 international has seen his role for Juventus become limited following the emergence of former Manchester United youngster Paul Pogba, and the Serie A champions would be willing to part with the player for £6 million.
Everton's interest has been hastened by Manchester United's official move for Fellaini, with David Moyes focusing his attention on the Belgium international with the club's attempts to sign Cesc Fabregas proving fruitless.
Manchester United have failed in two bids to prise the former Arsenal captain away from the Camp Nou and are prepared to break their transfer record in order to sign the player.
Barcelona, however, maintain they have no intention of selling Fabregas, and Fellaini would now appear to be the top target for Moyes following his appointment at Old Trafford.
Manchester United are reported to be locked in talks with Everton having made an offer of £23 million for the 25-year-old, and are hopeful of concluding a deal before the transfer deadline next month.
