Arsenal manager Arsene Wenger is now the longest-serving manager in Gunners history after surpassing the great George Allison's record of 13 years.
The Frenchman has transformed the club since taking charge in 1996, importing some of the best foreign talent and delivering high-quality attacking football on a limited budget.
Wenger has also overseen the building of the club's training facilities in 1999 and led the club into a new era at the Emirates Stadium at the start of the 06/07 season.
The man who plucked Wenger from relative obscurity in the Japanese J.League, former club director David Dein, has paid tribute to the legacy Wenger will leave behind when he finally retires. "His legacy will be that he has transformed Arsenal Football Club," Dein told Sky Sports News. "He has taken it to a completely new level but the style of football has been so entertaining.
"He changed their diet, training habits - he changed their lives."
The 59-year-old is also the club's most decorated manager, having won three Premier Leagues and four FA cups, including two doubles and an unbeaten season in 2004.
Wenger took the decision to concentrate on developing young players when the club's new stadium was being built to help ease the club's finances and now prides himself on player development.
The former Monaco coach has recently claimed he has no intention of retiring and turned down advances from Real Madrid over the summer, while his desire to deliver trophies to the Emirates remains as strong as ever.
