Nottingham Forest striker Jamie Paterson believes that his side can secure a Premier League scalp when they face West Ham United in the third round of the FA Cup on Sunday.
Forest are unbeaten in their last seven games and face a Hammers side struggling at the foot of the top-flight table at the City Ground.
Paterson told the club's official website: "We have had some tough games, when you look at QPR, Leeds and Reading - and a couple more before that as well.
"We have collected seven points from three games in the space of just a week and we are on a good unbeaten run, which we need to keep going.
"We are looking forward to the FA Cup game, when we will be looking to add another win to the run."
Billy Davies's side were knocked out in the third round of the competition last season by Oldham Athletic.
