Steve Davis gives us his post-match reaction from Bramall Lane following 2-0 defeat
"The players kept going and worked hard against a good side but I think it highlights the fact that we could do with getting a striker in. We could do with some help up there and have to try and find better than what we have because we haven't been getting enough goals. We had two good chances in the first half with Brad hitting the post as well, but it was only half chances ion the second half. ""The second goal, Jon Guthrie was tiring and he has switched off and before he knows it, Flynn is in behind him. He had that extra yard on him and he couldn't catch him and he took it well.
"I was disappointed with their first goal from the corner. It was poor defending from our point of view and we had talked to them about being alert to their short corners. We were sleepy, didn't react well enough and he has been able to drill it across our box. It could have been cut out, has hit Ben really and Flynn has prodded it home from close range.
"We had two chances in the first half and it was a brilliant double save from their goalkeeper to deny George and then Callum. I will have to see it again but he did well to keep them both out. It would have been nice for Callum to have scored on his first start for the club as it would have been great for his confidence. I wanted to see where he was in his development and he deserved his chance. It was a tough game for him starting at Bramall Lane against two experienced defenders.
Crewe boss Steve Davis told the club's official web-site: "We are disappointed to go out of the FA Cup, especially after having two goes at it. We didn't do well enough at home in the first game, so had to come here and that made it even more difficult.
Crewe Alexandra boss Steve Davis was left disappointed after two goals from Sheffield United forward Ryan Flynn saw his side exit the FA Cup at the first round stage. Crewe were left ruing those two first half chances that passed us by with Mark Howard producing a superb double save to deny George Cooper and then Callum Saunders. Brad Inman also hit the foot of the post after being put through by Anthony Grant.
