"Steven has nerves of steel, he has great confidence in what he does on the pitch.
"We always know that in important games he is capable of scoring at the end. This time it was a penalty, as it was against Portsmouth.
"I always have confidence that he has the calmness to score under that sort of pressure.
"He does well in training with penalties against Pepe Reina and Diego Cavalieri so we all have confidence in him."
