Billy Davies wants Nottingham Forest to follow Newcastle's example and learn how to kill games off.
The Reds boss was critical of his side for failing to take their chances in the 2-0 defeat at St James' Park.
Davies said: "They know how to dig in and grind out performances and that is the learning curve we have to get ourselves on now.
"We have to look at them and recognise that the difference between them and us is what happened when we had them on the ropes and did not take our chances.
"There are plenty of positives to be taken but, on a negative side, we must be more clinical. I`m not disappointed with how we performed, not at all, because this was another game we should have got something from. I am disappointed because of the little details.
"It was the final pass, the missed opportunities we had of scoring goals, it was our lack of composure, it was the way we gave the ball away at times."
