Nigel Clough was pleased to see the Blades advance to the second round of the FA Cup with a comfortable 2-0 victory over Crewe Alexandra in their first round replay at Bramall Lane on Tuesday night.
A goal in each half from Ryan Flynn paved the way for a deserved win, but speaking afterwards Clough was keen to emphasise the importance of Mark Howard's double save with the game goalless.
The Gaffer remarked "I thought we played well again, controlled the game and looked in command.
"But you always have that little worry at the back of your mind about Crewe hitting you on the break and they had two good chances in the first-half.
"Mark Howard makes a fantastic double save at 0-0, then they hit the inside of the post just after we have gone in front, but apart from that I don't think we were really troubled.
"Mark doesn't have to make save after save, but it is the sign of a very good goalkeeper that he is ready to make the saves when needed, he is a big player for us and certainly one of the best goalkeepers in League One.
"We were bright going forward at times, but again we just didn't apply the finishing touch to some of our moves."
Of Flynn's decisive double, the Gaffer added: "It was great to see Flynny get his two goals and even more pleasing that they both came in the manner they did.
"For the first one he is in the six yard box and shows desire to almost make a tackle to bundle the ball home, then he has made a great run on the back of some good passing in the midfield for his second and it was a very composed finish under pressure."
