The 24-year-old, who gave the ball away in the build-up to Villa's second goal, was honest in his assessment of whether he felt he had taken his chance.
"Not really," he said. "Morgan's only out for a week or so. I just tried to do well, and I'm not sure how well I did. I'll just have a think about it tonight and tomorrow."
Cork confessed his frustration at being dispossessed by Karim El Ahmadi ahead of Villa's second goal, admitting he was not at his sharpest.
"It was just a bit of rustiness from me," he said. "I sort of won the ball off him and then he sort of muscled his way through and got the cross in, so obviously I'm disappointed."
