Everton target Steven N'Zonzi was in London on Tuesday as he prepares a departure from Sevilla.
The former Stoke City midfielder travelled to the capital to visit his son with Sevilla's permission while representatives continue to make contacts with Premier League and Italian clubs over a January sale.
Sportsmail revealed on Saturday how Everton are monitoring developments as manager Sam Allardyce looks to strengthen the spine of his new side and add a left-back.
N'Zonzi fell out with coach Eduardo Berizzo when he was substituted in their 3-3 draw with Liverpool and has been left out of squads since.
