Former United midfielder Lou Macari shares his views ahead of Sunday's crunch clash...
What are your memories of playing against Liverpool?
Well, when I came to Old Trafford Liverpool had an exceptional side and they were the team to beat at the time. Things have changed in recent years, but back in the seventies it was about Liverpool, Kevin Keegan, Kenny Dalglish, Graeme Souness and co - they had a really great team. With that in mind, when you managed to get the better of them, you had done exceptionally well. Of course, my biggest memory is the FA Cup Final in 1977, not just because of the fact that we beat them, but also because we managed to stop them going on to win the Treble. They had a team at the time that was well and truly capable of going on to win three major trophies, but it was a day at Wembley where we had a little bit of luck on our side and thankfully we managed to beat them and stop them in their tracks.
Do you have any other standout moments against them, on a personal level, perhaps?
There were so many. I remember that all the games were fast and ferocious, I've seen a few on MUTV recently that I didn't remember from back then and there was no quarter given from either side - tackle after tackle. It meant everything to the players and equally so to the supporters. You were well aware of what it meant to the Liverpool supporters and likewise at Old Trafford, you knew exactly what it meant to our support.
