West Ham left-back Lewis Page has joined Sky Bet League One side Charlton Athletic on a deal until 2019.

The 20-year-old has been on loan at the Addicks' league rivals Coventry City for the majority of the season so far but joins Charlton on a permanent basis with the side 11th in the league table.

Page joined West Ham at the age of nine and went on to make his U18 debut in 2012, making 19 appearances over the course of the season.

Page made his first team debut in the Europa League at the beginning of the 2015/16 season and continued his fine form for the U21s, eventually earning a loan move to Cambridge United where he made six appearances.
