Sheffield United have signed St Patrick's Athletic defender Sam Curtis.

Curtis, 18, moves to Bramall Lane for an undisclosed fee.

"Sam is one for the future. We are looking forward to seeing how he progresses," boss Chris Wilder said.

"We spoke about players that we were signing in January as potential starters, but Sam is different and we could not turn down the opportunity to bring him to United."

Curtis also said: "I ultimately made the decision to come here because I think the club is on the rise and, obviously, Chris Wilder is back in as manager which is good.

"You can see that the club love him, and all the players really respect him. I do think the club is on the up, you can see that in recent performances, it is getting better game-by-game."
