Cardiff City boss Ole Gunnar Solskjaer was delighted with his defenders for their draw against Aston Villa.
Norwegian hopes an improvement at the back will ultimately prove the foundation for escaping the drop and an immediate return to the Championship.
"Ben Turner and Steven Caulker did as well as you can ask from two centre-backs in this game, that's where you take lots of encouragement from," he said.
"We had a solid foundation and that is what we have spoken about. Clean sheets give you a foundation to play off and that is more vital in this situation than anything else, and it gives you a platform to win games and you saw as a result we had more than enough chances to beat Villa."
