Butland watched on as Charlie Adam failed to convert the late penalty against one of the Potters’ relegation rivals at bet365 Stadium, admitting the 1-1 draw felt like a loss.
He told reporters: “It does feel like a defeat.
“The effort and intensity and quality of football that we played in the second half warranted a win.
“We have created chances, but unfortunately not managed to take them, and the penalty was one of those things – sometimes they go for you, sometimes they don’t. Unfortunately it didn’t go our way.
“But we move on, we stick together. There is no blame culture, we just get on with it and we prepare for Leicester [on February 24 at King Power Stadium].”
Butland has no doubt the Potters have improved since Lambert’s appointment as manager.
He told Stoke’s official website: “[We are] really, really pleased with the improvement in performances since the manager has come in.
“We are finally feeling like we are in games and can be taking points.”
