"We realise it`s going to be difficult and we are going to be underdogs. We have played nine times and won only once, but that was the most important of all. This will also be very important and hopefully we can win it again," admits Carragher.
"We will have to keep it tight at the back, because they do the same. We are similar because we are both strong at the back.
"You cannot afford to waste any opportunities because there shouldn't be too many in the game. To beat Chelsea you are probably going to have to keep a clean sheet, that is what we are looking to do."
