John O'shea expected nothing less from the England center back John Terry claiming that Manchester United must defeat Chelsea.
The Reds head into the game with four points clear of Arsenal in the title race and having a 15-point advantage over the Premier League champions, Chelsea.
O'Shea said: "He's got to say that, hasn't he?
"Obviously John Terry has to keep the season alive - and we still have to play them twice."
"We have the experience but we have to show it on the pitch, it's pure and simple."
United have not won at Stamford Bridge since 2002 and O'Shea says the result, rather than the performance, is all that matters this time around.
The Republic of Ireland international added: "It is definitely a case that the result is everything, especially when it comes to big weeks like this."
"Not many people are going to remember how well we played if we win. We are on top of the league at the minute and hopefully we can keep the cushion ahead of other teams. That obviously means not losing games and going to places like Stamford Bridge and getting results. We haven't had the most favourable of results down there recently but we are looking forward to the challenge of trying to put that right."
