Chelsea boss Thomas Tuchel says the must be perfect to beat Liverpool in Saturday's FA Cup final.
Chelsea lost against Leicester in last year's final and will begin as slight underdogs on Saturday.
Asked if victory at Wembley would compensate for a relatively underwhelming league campaign, Tuchel said: "I have to say it would make up for it big time.
"Liverpool do allow chances and we proved it with big chances in the Carabao Cup final.
"But it's their approach. They are the team who put other strikers of other teams into offside by far the most.
"So it's not easy to counter. You need the connection between the guy with the pass and the guy who receives it. But, like always, you can find solutions if you have a perfect day. We are hoping for it tomorrow."
