Awesome powerhouse of a player, whose ball-winning and passing skills help bind the Gunners' midfield together.
Played only two league games for AC Milan before Arsenal stepped in with a £4million offer for him - and what an inspired signing it proved to be as he helped the Gunners to the 1997/98 League and Cup double.
Arsene Wenger actually insisted that Vieira, along with Remi Garde, be signed by Arsenal before he took over as Arsenal boss. Vieira signed in August, and Wenger took over the following month.
Has had problems with discipline but since being sent off in the first two league matches of the 2000/01 season, he has altered his game without losing the physical edge. Card-happy referees please take note.
Has fantastic passing and tackling ability and also chips in with important goals such as the equaliser against arch-rivals Tottenham Hotspur in the 2000/01 FA Cup semi-final.
As well as being the heartbeat of the modern Arsenal side, Vieira is also a vital part of the French national side and the fact that he is a World and European champion says it all.
Seemingly disillusioned with the club's ambitions following the sale of Emmanuel Petit and Marc Overmars in 2001, the Frenchman started to talk of life away from Highbury.
The big Italian clubs have been joined in the hunt for Vieira's signature by Manchester United, it was reported. It is an indication of his worth that his biggest opponents value him so highly.
In the end Vieira signed a new deal with Arsenal, and he was then voted Carlsberg 'Player of the Year' a the end of the season and, though he was snubbed for the PFA poll, you won't find many people, players or fans, to disagree with the award.
The 2001/02 season saw Vieira win his second League and FA Cup Double with the Gunners. Also picked up the FA Charity/Community Shield in 1998/2002.
Was part of the France squad which failed so dismally to retain the World Cup in Japan and South Korea in 2002.
Was named as the new captain of Arsenal for the 2002/03 season following Tony Adams' retirement from the game. By that time he had played 277 games for the club, scoring 20 goals.
However, was harshley sent off for two bookable offences in September - and then handed a further two-game ban and £25,000 for saying referee Andy D'Urso had 'no personality'.
