Sir Cliff Richard has revealed he is still keen to top the American charts.
Despite 14 UK number one hit singles and a career spanning six decades, the 73-year-old pop legend insists he still wants to create a name for himself in the States.
Appearing on ITV's Good Morning Britain, Sir Cliff said: "There's a part of me that says how did I miss this, even though I had seven or eight top 20 hits, and nine top 40 hits, I'm still an unknown quantity here (America).
"It's still feasible that at my age I could find a niche in America. Not only I'm I still alive, I can still do it."
Meanwhile, the Summer Holiday hit maker, who has sold 250 million records worldwide, has also set his sights on doing a collaboration with One Direction, who have managed to crack America with three number one albums.
Talking about the potential duet he said: ''If they get through, if they're still here in 10 years' time, and want to work, they're good singers!''
Sir Cliff recently staged a free solo show at New York, after his joint gig with Morrissey was cancelled due to the former Smith's frontman falling ill.
Sir Cliff admitted he decided to press ahead with the gig at Gramercy Theatre because he wanted to remain loyal to fans.
"I was dejected when they rang me 10 days ago to tell me it was off. I was really down for a couple of days because I had looked forward to it so much.
"And the fans had too. And then I started reading about the fans being disappointed and I thought, wait a minute, we're all disappointed. Let's get together and be disappointed together. And get over it together.'"
