The striker has scored five goals in his last three games playing as a lone striker - a position his former manager told him he wasn't capable of mastering
Jermain Defoe says he has proven former Sunderland manager Dick Advocaat wrong after shining as a lone striker in recent weeks.
Defoe has scored five goals in his last three Premier League appearances to help Sunderland to crucial wins over fellow strugglers Aston Villa and Swansea City.
The 33-year-old's ability to lead the line for Sam Allardyce's side was called into question after he went seven league games without scoring in August and September.
But the former England forward always believed in himself, especially after the arrival of Allardyce in place of former coach Dick Advocaat in October.
"I knew that, given the chances, I would score goals. I always have done," Defoe said.
"Sam came in and I remember him saying, 'Jermain's a goalscorer, we all know that but in football you need more than that.'.
"So, yeah, it was frustrating but it was just down to me to show the manager that I'm good enough to play in the team - that I can play that lone striker role."
He added: "Dick pulled me aside, and he said, 'I don’t believe that, in this team, you can play up front on your own'.
"I said I'd been a lone frontman for England and for Tottenham and scored a lot of goals. I scored a hat-trick against Bulgaria at Wembley playing that role for England.
"Dick was like, 'well, that’s my opinion' and I was, 'I think you’re wrong'. Hopefully Dick’s watching the games now."
