However, the Blues boss was highly critical on the state of the Bloomfield Road pitch after the 1-1 draw on Tuesday night.
"We didn't manage the pitch because the pitch was difficult for both teams. Blackpool did the right thing in the first half," Clark said.
"Overall the attitude and application and defensive side of the game for the full game I was happy with.
"The attacking side was a big improvement in the second half. We had to cause them more problems because we hadn't caused them any problems in the first half.
"The state of the pitch is unfortunate for both teams because I think there are lots of good footballers on both teams."
