Manchester United boss Sir Alex Ferguson has been described as a visionary by Arsenal counterpart Arsene Wenger.

Ex-United defender Gary Neville said: To be at this club for so long is staggering. You would never believe it could happen. "I've said before, United had Sir Matt Busby, now they've got somebody who's replicated his longevity at the club and surpassed his success - you would just never believe it could be achieved."
