"We were a bit tippy-tappy and apart from a ten-minute spell in the second half when they pressurised us, we deserved to win,'' he said after the 3-0 win at The Stadium Of Light.
"I'm delighted for Tommy Smith. People were getting impatient because he hadn't scored and I'm pleased to have Jason back from injury.
"He's scored twice in three games since his return from injury. He is a real asset to us when he is fit and I know I can depend on him.''
