Charlton Athletic have signed Conor Coventry from West Ham United for an undisclosed fee.
The 23-year-old midfielder has signed a three-and-a-half year deal with the League One club.
Coventry, who made his Premier League debut last season, previously played under Charlton manager Michael Appleton while on loan at Lincoln City.
"I'm delighted to be able to be reunited with him on a permanent deal," Appleton told the club website.
"He's very, very comfortable on the ball and knows his position really well. He's a good passer of the ball, with good technique, and he's got a steeliness to him as well which I like - a bit of nastiness to him.
