The former England Under-21 international is aiming for an call-up to the senior squad in the future after his second season at centre-back for Hamburg
The former Chelsea man played 21 games for Hamburg this season, and has insisted he is happy playing his football in Germany after establishing an important centre-back partnership with Heiko Westermann.
Hamburg were unable to qualify for the Europa League this season, finishing 7th in the Bundesliga, and Mancienne admits it might be hard to to get noticed by his international manager.
"You have to be playing Europa League or Champions League [football] to really get recognition," he told the Daily Star.
"That's a key thing and what Hamburg are aiming for this year. But if you are playing well they should still be watching you.
"I don't think you should drop off the radar if you play abroad."
Mancienne has represented England at every age group except senior level, but despite speculation he insists he is happy with life in Germany."I'm really settled," he said. "I haven't thought about moving or coming back to England. I'm really enjoying my time here."
