Was it Lee Novak's 10th of the season or loan defender Neil Trotman's first? "Both are claiming it but I'm not bothered," said Clark after a second win on the road inside a week. "The point is we won, kept a clean sheet and could have had more goals.
"We thoroughly deserved three points. There were lots of good aspects about our performance. We combined determination with some flair," added Clark, who bemoaned the early loss of Lee Peltier with a shin injury.

Pool's best moments were in the opening minutes and in the early stages of the second half but they could not beat Alex Smithies, who pulled off outstanding blocks, notably against Dean Behan.
Peter Clarke and Trotman were staunch in central defence and Tom Clarke underlined his versatility as Peltier's replacement.
Early Pool pressure was broken when goalkeeper Scott Flinders upended Jordan Rhodes for Gary Roberts to convert a 15th-minute penalty and from then on it was largely Town who called the tune with Danny Drinkwater and Antony Kay controlling midfield.
The game was as good as won in the 66th minute when Novak met a corner from Roberts, the header striking the underside of the bar and referee Anthony Taylor appearing to signal a goal a split-second before Trotman made sure.
