Sturridge spent the second half of last season with the Baggies, but managed just two league starts as they were relegated to the Championship.
Despite playing so few matches, suffering another injury that sidelined him for two months and failing to help West Brom beat the drop, Sturridge said the spell away from Anfield was just what he needed.
“It was good," said the England international. “I don't regret anything. The experience made me grow as a person. That's what it's all about. Evolving as a man, evolving as a footballer.
“From the outside looking in, you can also improve. When you're on the inside looking out, you sometimes don't get to see what you have to do to get to the next level – how you need to change your game. When you're on the inside, you don't see it. When you're on the outside, you can assess things differently.
“I've always been hungry. The hunger will never change. I'm taking every day as it comes with a positive mind-set. That's all I'm going to do."
