Manchester United has been cruising through this Premier League season with a 12-point lead at the top of the table. But today will mark their greatest test since the 2012-13 season kicked off eight months ago. Today one of the giants of world soccer will be knocked out.

No matter where you’re watching this match today, the world’s attention will be locked on Old Trafford for two hours where Jose Mourinho says the “world will stop” to watch the game.

And no matter what happens, Sir Alex Ferguson says we should be able to see Ryan Giggs make his 1,000th senior appearance tonight. What an honor.

Man United team v Madrid: De Gea, Rafael, Ferdinand, Vidic, Evra, Carrick, Cleverley, Nani, Welbeck, Giggs, Van Persie
