Leeds suffered a 1-0 defeat at the hands of Stoke City at the bet365 Stadium on Wednesday night.
The Whites again conceded from a corner after the ball went in off Pascal Struijk after hitting the crossbar to give Stoke the decisive lead in the 80th minute.
Patrick Bamford missed a penalty earlier in the second half but Newsome admitted that Stoke made it difficult for Leeds by pressing them high and stopping them from getting into any passing rhythm.
However, he stressed that teams are finding it too easy to take advantage of Leeds from corner and set-piece situations and it has become a major problem for Daniel Farke’s side this season.
Newsome said on BBC Radio Leeds: “Teams will watch us.
“Stoke had watched us, they have obviously seen what we are and they had a game plan.
“They wanted to stop us from playing out from the back, they pressed us high and we found it difficult to play against them.
“And set pieces; it’s funny every team we play against put lots of bodies in and around the goalkeeper and the six-yard box and have joy with those corners.
“That’s an Achilles heel for us at the moment.”
Leeds are still third in the Championship table but the gap to the top two has further widened.
