Friedel will be 39 in May but his powers so show no signs of diminishing.
Oldie but a goodie: Friedel has been plying his trade in the Premier LEague for 14 seasons
He produced crucial late saves to deny Newcastle an equaliser inSunday's 1-0 win which pushed Villa five points clear of the bottomthree.
Friedel has already held talks with Villa over a new contract with his current deal running out this summer.
Collins said: 'Since I came to the club, Brad has been unbelievable week in and week out. He is such a good professional in the way he handles himself off the pitch and he is in the gym every day still at nearly 40.
'He is a credit to himself and his professional and his professionalism is second to none.'
Collins, who scored the winner against the Magpies, added: 'I think I will retire before him the way he is going and I'm only 27!
'He is a world-class keeper and can go on playing. When he is called upon, if he has made 100 saves or no saves in a game, you can always rely on him.
'He has been doing the same thing for years and years in the Premier League.'
