Steve Thompson bemoaned Blackpool's first-half performance following a 2-1 defeat to Charlton at The Valley.
The Seasiders' caretaker boss admitted that the display lacked a cutting edge, until Nathan Eccleston pulled a goal back in injury-time.
"In the first-half we never got going. We came here with a game plan to try and get certain individuals on the ball in midfield to try and get good movement up-front. It was tippy-tappy football with no end product," he said.
"They've got a system that suits them, which is a 4-4-2 so we had to pass the ball and break the line down and get into pockets to play round them. In the first-half we looked flat and a little bit leggy and although it was nice to watch, we had no end product, no crosses and no shots on goal. I've told the players that you can't start games like that.
"We got into them at half-time about certain situations and expectations. It was a lot better but the first goal was vital today."
Thompson took charge of the team following Michael Appleton's departure to Blackburn Rovers, with the search now on for the club's third manager this season.
"The last couple of days have not helped us, it's not an excuse but it's just another disappointment for that bunch of lads in there. We've got to get some stability now," he added.
