Arsene Wenger, Arsenal's longest-serving and most successful ever manager, is to step away from his job at the end of the season after 22 years at the helm.
Wenger has won three Premier League titles, an all-time record seven FA Cups, two doubles, reached the 2006 European Cup final and went the entire 2003-04 Premier League season undefeated, but has faced opposition over recent seasons due to the repeated failure to challenge for either the Premier League or Champions League.
Arsenal are still in the semi-finals of the Europa League but, even with the possibility of returning to the Champions League through that competition, a decision has been made to end the uncertainty that has hung over the club in recent months.
A new backroom structure was already in place and candidates are being assessed as Arsenal now attempt to deal with one of the most seismic moments in their history.
Wenger confirmed the decision this morning and, as ever, he stressed the importance of maintaining the values he has embodied in his time in English football.
Put simply, that is an entertaining style of football, opportunities for young players and a fiscal structure that safeguards the club's long-term future.
Following Wenger's announcement, we've taken a look at the 10 best signings Wenger made during his time at Arsenal.
