He was excellant for Coventry in a 442 and was excellant at the world cup (granted Mcgrath was so good Baggio put him in his team of the world cup, I'll never forget the passage of about 30 seconds when he cleared 3 balls in the box in a row)
And being the super chalkboard master you are you can appreciate it is completely different being 1 of 2 central defenders in a 442 and being asked to play in a wide position of back 3 when you have had zero coaching in it.
Couple that with the wing backs we had at the time and our attack minded set up and you can see why not just Babb but most Liverpool defenders struggled in that period.
