Ben Osborn said that Nottingham Forest will go to Stamford Bridge and give it a go as they aim to dump Chelsea out of the Emirates FA Cup.
Forest knocked out the holders at this stage of the competition last season and Osborn is hoping for more of the same this time around.
He said: "We beat Arsenal last year in a great game and we have to look to that and see what we can do when teams make changes in the FA Cup.
"We will go there, give it a right good go and hopefully we can cause an upset.
"The fans are going there for a good day out and hopefully we can give them something to shout about. We will aim to stay in the game for as long as possible and try and cause them some problems.
"It will be great; I love the FA Cup and I think it is the best competition in the world. Speaking to some of the other lads as well, they love it so I think it will be a good day out for everyone. We just need to put in a performance and make everyone proud."
Osborn expects Chelsea to make some changes to their side and hopes to take full advantage of that against the cup holders.
He said: "They have a good team but I am assuming they will make changes, so there will be players who haven't had a lot of game time.
"If we can start bright and frustrate them, and we have put in some really good performances away from home, so we are confident in that respect. Hopefully we can create some chances and make it hard for them."
