Henri Lansbury has joined Nottingham Forest on a permanent deal for an undisclosed fee.
The 21-year-old midfielder, who has been associated with Arsenal since the age of eight, made a total of eight senior appearances for the Club.
Lansbury featured three times in the Premier League and five times in the League Cup, where he also scored his only first-team goal for Arsenal in the 4-1 third-round victory at Tottenham Hotspur in September 2010.
The Enfield-born midfielder spent last season on loan in the Championship at West Ham United, where he made 22 appearances to help the Hammers to promotion back into the Premier League via the play-offs.
An England Under-21 international, Lansbury also enjoyed loan spells with Scunthorpe United, Watford and Norwich City during his time at the Club.
Everyone at Arsenal would like to take this opportunity to thank Henri for his contribution to the Club and wish him well in his future career.Copyright 2015 The Arsenal Football Club plc.
