Medical underway: Everton player signed for £6m in 2017 agrees 20-21 exit - Sources

Everton defender Lewis Gibson is undergoing a Reading medical this afternoon after agreeing the terms of a season-long loan, Football Insider understands.

Gibson, 20, spent the second half of last season on loan at League One side Fleetwood Town after failing to break into the Toffees side.

An Everton source has told Football Insider that the young defender is now heading to the Madejski Stadium for a season in the Championship.

The terms of the 2020-21 transfer have been agreed and Gibson is now putting the finishing touches to his second temporary move of the calendar year.

He is a left-footed centre-back and regarded as a player of immense promise by his parent club.

Gibson signed from Newcastle United in 2017 for a potential £6million if all add-ons are achieved.

The youngster signed an extension to his Everton contract in January – tying him to the club until the summer of 2022 – before heading out to Joey Barton’s Fleetwood.

His exit comes as Everton boss Carlo Ancelotti scours the market for a fourth senior centre-back after losing Mason Holgate until potentially the end of October due to a toe injury.

This site revealed last week that the Toffees have turned their attention to centre-back Gleison Bremer as an alternative to Chelsea’s Fikayo Tomori.

The Brazilian, 23, has three years remaining on his Torino contract and is open to a move to the Premier League.

Carlo Ancelotti paired Michael Keane and Yerry Mina at centre-back for their opening two Premier League matches, both of which they won.
