MOTD COMMENTATOR’S NOTES

The first mega-match of this season’s FA Cup comes early, featuring the competition’s best ever sides, whose previous clashes have provided some of its most iconic moments.

Alan Sunderland….Ryan Giggs….their joyous, sprinting celebrations – many of us don’t need to YouTube search to ‘see’ them.

It really could be a tie to give us new memories too, with both sides full of confidence having shown in the last fortnight that they can beat fellow ‘big guns’.

Yes, we’ll enjoy the ongoing drama of their Premier League race for the top four, but you can’t beat a game with instant jeopardy – the feature film version of a smash hit series.

Get the popcorn in.
