Southampton keeper Davis: Sunderland tough place for players if they're struggling
The 37-year-old endured a tough year at Sunderland and left for St Mary's following relegation from the Premier League in 2006.
"It wasn't a successful period in my career, but I certainly look back on it as a learning period in my career," Davis told the Daily Echo. "There are things that I learned while I was there that I use today and obviously make you stronger and give you different experiences.
"It's a fantastic club and a fantastic stadium, and when things are going well there everything goes well - but, likewise, when it's not going so well it can go the other way, and that's a certain situation for them at the moment that affects them.
"They've changed their manager and they're certainly in a difficult period at the moment, but it's of no interest to me as we're just looking to progress into the next round of the cup."
