Leicester City boss Nigel Pearson has said that his side must be at their best in order to challenge Chelsea at Stamford Bridge this afternoon.
Pearson, whose side are coming off the back of their first win in three games, admits that there is more to the FA Cup than being the underdogs and has urged his side to give a good account of themselves.
"We'll have to be at our best," he said. "But it's a chance for us to show what we can do.
"It's not all about us being underdogs, we want to go there and give a good account of ourselves and cause them problems.
"We've got to be competitive. It's about understanding the strengths of the opposition."
The Foxes are the last remaining non-Premier League side in the competition.
