Is This Arsenal's Greatest XI?
CM. Patrick Vieira

It's been close to a decade since he left the club to go to Serie A giants Juventus, but he certainly had his best years while playing at Highbury. The great thing about Vieira was his versatility. If teams fancied themselves a little bit and figured they could defeat Arsenal in a true game of footie then he had the ability to control the middle of the park with good technical play. However, if it was a war teams wanted to get in, then Vieira was more than willing to get in a battle to prove that he and his team were no pushovers. These were the qualities that epitomised the Invincibles team Vieira captained in the 2003-04 season.
They say that no player is irreplaceable, that if they leave then someone will take their place and do their job. However, Vieira leaving left a gap in the Arsenal midfield that even after nearly 10 years they've still never really been able to fill.
