The Canaries meet Sir Alex Ferguson's side at Old Trafford on Saturday, and the on-loan Sporting Kansas City forward thinks that United will be wary of the threat he poses following his goalscoring exploits against Everton.
"I may be a marked man against [United] next week now," Kamara is quoted as saying in The Times.
"That actually makes it a lot of fun for me. [Sporting Kansas] played United when we were known as Kansas City Wizards, when they were on a pre-season tour of America. We were the only team to beat them [on the tour].
"I scored and got the assist in a 2-1 win. [Paul] Scholes and [Ryan] Giggs were playing and [Dimitar] Berbatov scored their goal so all their top guys were playing."
Chris Hughton's side are currently 12th in the Premier League.
