Dean Ashton has said on Goals on Sunday, broadcast on February 21 at 11am, that Jack Collison must take his time in adjusting to his retirement from professional football.
Last week, the former West Ham United midfielder announced that he was ending his playing career at the age of 27 after failing to overcome persistent knee problems.
In 2009 Ashton, who also plied his trade for West Ham, retired in similar circumstances at 26 after long-term issues with his ankle. He made 56 appearances for the East London side in just under four years.
The former England international has admitted that he struggled soon after ending his time on the pitch, and has advised Collison in how to deal with the change in lifestyle.
Ashton said: "When you shut that door, it's all about trying to cope mentally, and I struggled for the first two years, and I'm sure Jack will do as well.
"The biggest thing for me is, if you ask anyone in the public about what is their favourite thing to do and the best thing you are good at, and then tomorrow, you can't do that ever again, everyone would really struggle with that.
"You're also known as Dean Ashton or Jack Collison the footballer, and that is your life. Everyone evolves around you and you being right for the Saturday. People will move across the country for you. It's all about you.
"When that stops, you have to take time to find yourself and find out what you are like away from football. You find out out that there is life after football."
Collison currently works on the coaching staff at Peterborough United, where he played 12 times in 2015, while he has also said he hopes to progress in the media side of football.
