I agree. I've just wasted some more of my time by looking at the MOTD 'highlights' and from what little you can see if looks as if Barnes's goal cones off the point of his shoulder, of the very top of his sleeve and above the flesh. Poor goalkeeping in my opinion but McCarthy can't be criticised these days.
As for his 'handling outside the box' again, not clear or obvious . If you accept that he has both hands on the ball then the attempt to kick the ball is a foul on the goalkeeper.
All minor points in a long season.
