WATCH: Alex Ferguson takes the p*ss out of Tinie Tempah’s jacket before the FA Cup Final

You know you're in trouble when a 74-year-old is ripping into your threads.

Tinie Tempah's performance prior to the FA Cup final on Saturday may not have been to everyone's taste, but Sir Alex Ferguson seemed more pre-occupied with the rapper's shiny garb. The FA have shared fascinating pre-game footage from Wembley's 'tunnelcam' via their YouTube channel, and some of the most revealing footage features a good-humouring Fergie. He is seen welcoming the players, and even joking with Alan Pardew and Mark Clattenburg about bribing referee (a gag that is probably less funny to Pardew in hindsight). But amidst all the football lark, there was an amusing culture clash when Sir Alex encountered Mr Tempah. The legendary manager couldn't take his eyes off Tinie's Bacofoil-like silver jacket. "How much did that jacket cost? How much did you pay for that?!" Credit to the musician, he took the questioning in good humour. Perhaps Fergie fancied a space-age bomber jacket of his own... https://www.youtube.com/watch?v=iIoONpB3Hts https://twitter.com/EmiratesFACup/status/734144488436826112
