Who said this about preparing to face Arsenal? "Parts of my body that had had previous injuries would be aching. And it was because my body knew I was getting ready. It was saying - I'm going to suffer."
Answer: Roy Keane, in the recent ITV documentary about his battles with Patrick Vieira, who is now performing a role for Manchester City that he ought to be filling at Arsenal. Like Paul Scholes - who rattled Jack Wilshere with a televised critique of the young midfielder's supposedly stalled development - Keane remembers playing Arsene Wenger's teams as a physical and spiritual ordeal. Scholes, meanwhile, was always needled by the regal bearing of Thierry Henry and co.
Nine years ago Arsenal won their most recent trophy: the 2005 FA Cup, beating United on penalties at Cardiff's Millennium Stadium.
Another country, another era. Hull City's players talk of nerves, excitement and being the underdogs. But few would be likely to reach into Keane's vocabulary of pre-match dread. The 2014 Arsenal FA Cup side are not blessed with the steely character that marked them out before Jose Mourinho's Chelsea replaced them as United's biggest rivals.
"Very, very, very tough," was Keane's description of Vieira, who played alongside Cesc Fabregas and Gilberto Silva nine years ago in an Arsenal starting XI that could find no room for Robin van Persie, Sol Campbell, Edu or Freddie Ljungberg. The mischievous website clock shows how long Arsenal have waited to feel metal on their fingers. But it reveals nothing of how much the team and the club have changed since that 5-4 penalty shoot-out win in Wales.
