Everton target Allan will travel for pre-season with Napoli despite rumours continuing over his future with the club.
Carlo Ancelotti is keen to bolster his midfield options in the transfer window and has identified one of his former players as someone who can improve the squad.
The Brazilian worked with the Blues boss at the Serie A side and has been the subject of a litany of transfer rumours over past weeks and months.
Reports from Italy suggest that an agreement is close to bring the midfielder to Goodison Park, although the latest developments from Napoli might suggest otherwise.
The 29-year-old has been included in the squad for the Serie A side's pre-season retreat to Castel di Sangro as the Blues still wait for their first senior signing of the summer.
Everton are expecting to have to be patient in landing the players on their wish-list with a growing belief that most Premier League clubs may only start doing most of their business in the final two weeks of the window.
Ancelotti is believed to be calm over the club's transfer plans despite a lack of senior signings up until this stage.
The Premier League transfer window closes on October 5.
