Barry can do all things the other midfield players can't do week in week out and calm everything down.
1, defend
2, pass the killer ball
3, take free kicks and corners
4, pull the others into line
5, be a captain
To top all this off he knows better than most how Villa runs and the kids have somebody around to learn from that's been there done that got the t shirt.
IMO Villa/Lambert missed out good and proper here
