Charlton Athletic have signed West Ham United midfielder Conor Coventry.

Coventry joins for an undisclosed fee and has signed a three-and-a-half-year deal with the League One club.

"I'm delighted to be able to be reunited with him on a permanent deal," Addicks boss Michael Appleton told the club's 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.

"He's one who lives his life right and is a proper professional."
