Goalkeeper Joe Hart took the blame for conceding the equalising goal as England had to be content with a 1-1 draw from their delayed World Cup qualifier against Poland.
Hart failed to make contact when he came to punch clear a corner which allowed Kamil Gilk head in and cancel out Wayne Rooney's first-half opener with 20 minutes left.
"I came and didn't get there and the lad did a decent header," Hart told ITV Sport.
"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."
England captain Steven Gerrard was also reasonably happy to escape from Warsaw with a point.
