We'll come up against 'Walks' when we travel to Leicester City's Walkers Stadium for the first time in the Premiership on Sunday.
Goalkeeping coach Hans insisted Ian's professionalism was spot on despite losing his number one slot to Neil Sullivan.
That attitude paid dividends for him when he moved to Leicester City after the 2000-01 season - he's now back in the England squad.
"I thought Ian was superb," reflected Hans. "His attitude was excellent because when Neil Sullivan came in and did very well he didn't get a sniff.
"But he was always focused on the job even for the reserves and it's hard for an international to motivate himself for that.
"I always said to him 'you never know what is around the corner' and it proved that way because Leicester came in, he's played well for them and now he's back in the England squad.
"Good luck to him. He worked hard to be where he is now. The most frustrating thing was to sit on the bench - you can earn all the money in the world but if you are a player, you want to play and that's how it's turned out.
"It's good to see doing well and he's a nice fella as well, I had a few years with him and I really enjoyed working with him."
Hans Segers says he couldn't fault Ian Walker's attitude and application during a tough final year at the Lane.
