Frank Lampard insists Chelsea must ruin relegated Portsmouth's hopes of a fairytale end to their dismal season with a ruthless performance which would secure the Blues a place in the history books.
Pompey's financial problems forced the club to enter administration and they now face life in the Championship next season after their relegation, but a surprise win over Tottenham in the semi-finals has given former Chelsea boss Avram Grant the chance to pull off one of the biggest cup final shocks in history.
"We don't want it to be a fairytale that goes all the way for Portsmouth, we have to be ruthless how we approach the game," said Lampard.
"To win the league was a huge thing for us last week. We got that job done but we knew the season wasn't over.
"We saw Portsmouth against Tottenham in the semi-final and we've seen them have a very spirited end to the season, even with the difficult circumstances.
"What better way to go to the World Cup than having done the double? It's very exciting for all the players here who are going to the World Cup, regardless of their country.
"But I would hate to go there having missed out on the double. Mentally if I went away and we'd lost that would be the freshest thing in the mind and it would be horrible. We are determined to finish the job and it won't be as easy as some people have made out. I also have a lot of sympathy with Portsmouth.
"I think they've handled themselves very well, particularly Avram Grant, who we know really well and have a lot of respect for.
"He's handled himself brilliantly and everyone has seen that. It's not been easy circumstances and everyone has taken to them a bit this year - in very adverse circumstances they have held their heads high and managed to get to Wembley.
"But the double is huge and has never been done in our history. We really want to do it. I grew up always knowing the big teams that had done the double in the '70s and '80s, so if we do it, it will go down as the best year in the club's history."
