The former Manchester United defender believes that the Black Cats did not help themselves against Chelsea but says that they still showed spirit despite defeat
The result sees the Black Cats lie in 18th position in the league table, with just 13 points accrued from 15 games, and while O'Shea believes that his team showed determination, he admitted that they did not help themselves.
"We showed great character to come back into the game," he told the club's official website. "There were some good chances created and [Petr] Cech made some fantastic saves."
He continued: "We had to show a bit of character at home in front of our own fans. I don’t think we’ve ever laid down and let teams streamroller us.
"That’s a small positive to take, but we did help Chelsea out with the goals and made it a hard road for ourselves."
Sunderland will play Reading on Tuesday December 11 and the Ireland international believes that it will be a 'huge game' for the Black Cats.
"We have to look forward to Tuesday now. It’s a huge game as we all know and hopefully we can get something positive from it," added O'Shea
