Everton have enquired about Roma's Robin Olsen as they look to sign a goalkeeper on deadline day.
Any deal for the 30-year-old Sweden international, who spent last season on loan at Cagliari, is likely to be a loan.
The Toffees have also enquired about Manchester United's Sergio Romero and Tottenham's Paulo Gazzaniga.
The club want to provide competition for England number one Jordan Pickford, who has recently made several mistakes.
Manager Carlo Ancelotti said a new goalkeeper was not a priority last week but 26-year-old Pickford's latest error, which cost a goal in the 4-2 win against Brighton on Saturday, has prompted a rethink.
Romero, 33, is third choice at Manchester United behind David de Gea and Dean Henderson and would welcome a move to Everton, while 28-year-old Gazzaniga has been pushed down the pecking order by Joe Hart's arrival at Spurs.
The Toffees have already signed one player on deadline day, with defender Ben Godfrey joining from Norwich in a deal worth an initial £25m.
