England goalkeeper Joe Hart took responsibility for conceding the equalising goal as his side were held to a 1-1 draw in their World Cup qualifier against Poland.
Hart failed to make contact when he came to punch clear a corner which allowed Kamil Gilk to head in and cancel out Wayne Rooney's first-half opener with 20 minutes left.
The Manchester City keeper shouldered the blame for the leveller, admitting it proved costly.
"I came and didn't get there and the lad did a decent header," he said. "It's my fault, I should have punch it or stayed in goal. I didn't do either and it cost us."
Regarding the result, Hart added: "We've got to believe that's a good point.
It's a tough place to come."
Rooney, whose goal marked his 32nd for his country, pulled no punches about England's below-par performance, admitting they will have to improve on their showing against the Poles if they are to qualify for Brazil 2014.
The Manchester United striker said: "It was a hard-fought point. It was a difficult game, a difficult pitch. We weren't at our best but we dug in and got a draw.
"We know we can play better but this is a difficult place to come. It is a decent point.
"We knew it was a tough group, but we're confident. We believe in ourselves and we believe we are the best team in the group, so we are confident of qualifying.
"Do England have to improve to qualify? Yes, of course. We know we can play a lot better than tonight but at least we got the point, so we can take that home."
