Wayne Rooney believes Manchester United can take confidence from the way they came back from 3-0 down against Chelsea to win a point.
Jonny Evans' own goal put Chelsea ahead by the interval and two rapid goals after the half-time break from Juan Mata and David Luiz put the home side in control.
Yet United's famed ability to fight back was again on display as Rooney scored a brace of penalties before substitute Javier Hernandez headed in a late equaliser.
However, Rooney was disappointed United lost vital ground in the title race with neighbours Manchester City.
"It's two points lost," Rooney told Sky Sports 1.
"We understand that, but after being 3-0 down - the City players at home must have liked that - we enjoyed the way we fought back.
"A lot of teams might have put their heads down and accepted defeat, but we never put our heads down."
Rooney claimed he did not see the penalties, but was confident of converting both.
"The two (penalties) we got I'm not sure. Thankfully the referee gave them," he said.
"I was always confident. I waited for the keeper to make his move and put it the other way."
