It would be nice if they did send the team that last played in a European Cup Final, but it is more likely to that they send another side as suggested above.
I am no United fan, but we should be grateful they send a team down because it is not really helping their own preparations that much or enhancing the football 'education' of their youngsters to any great degree.
Last season we had great difficulty even getting the ball off what was probably their A team and this goes to show the quality of young potential Premiership footballers. Even if you have never heard of the players on the pitch, you can almost guarantee to see good football (contrast with Histon a few days later) and a real test for Altrincham
