"After going a goal down within a minute and a half the lads showed a lot of character," Clark said after the match.
"How we were still a goal down at half time I couldn't understand because we put in a magnificent performance.
"We showed a lot of quality on the ball so I was delighted and we could have won it.
"We showed we could compete with the best because Leeds are the best team in League One at the moment.
"We have come to their patch and matched them.''
