Kevin Keegan: "It's a chance for the players here to test themselves against the very best, probably for the first time this season playing one of the top-four sides while we are in a run or form and while we have got some confidence.
"There's no doubt that should help us. Now whether that will help us enough to play for 90 minutes-plus against a side of Chelsea's calibre and get us a result, that's what we don't know.
"But we are going into the game with an awful lot to play for. We are playing for the biggest thing of all, we are playing for pride.
"There is no doubt about it, Chelsea will expect to come to Newcastle and get something - that's why they are at the top of the league.
"But expecting it and getting it... there is a game of 90-odd minutes in between that needs playing.
"We have a good record against Chelsea at St James' Park over the last few years, so that in some ways will be an inspiration to us.
"But it won't be enough on it's own to help us win. We need a performance, we need to show ourselves in a good light and we need to pick up, I guess, a Tottenham-type performance.
"That, with the crowd behind us, will see us give them a hell of a game.
"If they come through that and they become champions in the next week, 10 days, they will deserve it."
