Danny Sturridge credits Liverpool boss Brendan Rodgers for his career turnaround.
The striker is tipped for a big World Cup with England.
"It was the same when Owen Coyle took me on loan for Bolton. I had the belief from him and I just wanted to do as best as I could for him," he told the Daily Mail.
"It's the same with the gaffer now. He's put belief in me, he's a world-class manager, he's unbelievable. Tactically unbelievable. Your mentality changes without knowing it, and the more and more you work with him the more and more it just happens naturally."
Rodgers suggested that Sturridge should work with Dr Steve Peters, the sports psychiatrist now assisting Roy Hodgson with England.
"He's a great man," says Sturridge. "I enjoy talking to him. The gaffer said to me I should see him, to be at peace with myself after some of the stuff I'd been through. When I arrived at Liverpool my confidence was low. Now I'll even speak to Steve on the phone or on Skype."
