Sebastian Larsson: "We have beaten them three times in a row, but what a team they are and what a fantastic game to play in.
"At home, in front of a big crowd backing us, we have shown we can do it as we have beaten them before in previous seasons.
"We know we have the confidence of beating them before, but if we are being honest we will have to play the perfect game to beat them again. Why not do that on Sunday?
"It will need all of us, from one to 11 to be at our very best to get a result, but we can do it as we have shown in the past.
"It's all about breeding confidence and we have won two out of our last three now which sounds a hell of a lot better than it has done for a while.
"That's the way you need to look at it and gain confidence because confidence is such a massive thing in football.
"It can disappear very quickly and gain it maybe not as quickly, but I think we are gradually beginning to build up a little bit of confidence and a win in the cup will not do us any harm at all."
