Smogs In Bitter Battle With Man Utd!
Middlesbrough FC's Gary Smith and the club have admitted liability for the career-ending tackle in May 2003.
The hearing at Manchester High Court is to decide the level of damages.
Ferguson, speaking at the first day of the hearing, said: "I thought the boy showed fantastic focus, a great attitude to work hard, and they are qualities to give any player an outstanding chance in the game.
"His attitude was magnificent. It was sad to see him come back and try so hard.
"I think we knew at that point it was a fruitless task, but he's an example to a lot of young players who get injured."
Earlier, the court heard claims that Collett, 23, could have earned more than £13,000 a week, making a total in excess of £16m, if he had played until the age of 35.
The hearing continues.
