Stan Collymore has congratulated Arsenal manager Arsene Wenger on Twitter after the Frenchman celebrates 20 years as Gunners boss.

The 66-year-old took over in North London back in 1996, after manager Bruce Rioch was sacked after his relationship with the board had become untenable.

Outspoken former Liverpool and Aston Villa star described Wenger’s tenure as “a magnificent achievement” on his personal Twitter account.

The former Monaco and Nancy manager has guided the Gunners to three Premier League titles during his 20-year long stay, including the famous 49-game unbeaten run which is now known as the Invincibles.

Wenger arrived in North London as a relatively unknown manager, after joining from Japanese side Nagoya Grampus Eight. However, two decades down the line, the Gunners boss will be looking for his 619th win in all competitions against Burnley on Sunday.

After six FA Cups, six Community Shields and a Champions League runners-up medal, Wenger has broken a multitude of records during his time at Highbury and the Emirates.

Wenger is the longest-serving foreign manager that this country has known, following 15 trophies and almost £700million spent on new talent.

Sunday’s face off against Premier League new boys Burnley will be his 1075th match in charge, and three points will move the North London giants into second place if results go their way.
