Chelsea skipper John Terry claims that the pressure will be all on United at Stamford Bridge on Tuesday and the England star insists the Blues can still manage to win back-to-back titles.
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.”
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.”
