DANNY Lafferty has completed a permanent move to Sheffield United for an undisclosed fee.

The 27-year-old has signed a two-and-a-half-year deal having spent the first half of the campaign on loan at Bramall Lane.

Northern Ireland international Lafferty leaves Burnley having made 45 appearances for the club since his arrival from Derry City five years ago.

He had previously had spells on loan at Rotherham United and Oldham Athletic and has featured 21 times for the Blades so far this season, scoring once.

Sheffield United boss Chris Wilder said: "Dan has been brilliant for us and he is another who has played a big part in helping us get to where we are now.

"He is an international footballer who has played the majority of his football in this country in the Championship and he has proved himself to be a dependable performer.

"Dan has been part of the success Burnley have enjoyed over recent times and I'm delighted and thankful to our board for their continued backing."
