Chris Wilder has added a further attacking option to his squad, with the loan signing of Chesterfield's Jay O'Shea.
The Irishman, who is out of contract in the summer, joins the Blades until the end of the season. The paperwork was completed on Tuesday morning.
The attacking midfielder, 28, has been at Chesterfield since 2013. He arrived on these shores with Birmingham City and after a number of loan spells he joined MK Dons. He helped Chesterfield win League Two and scored 42 goals in 161 starts at the Proact Stadium.
Of O'Shea's arrival, boss Wilder remarked: "Jay is someone we've monitored for quite a while now. He is a very good footballer, capable of playing in several attacking positions.
"He plays centrally or in wide areas and we're confident he will create chances and score goals too. He gives us options and versatility and has been a standout performer when Chesterfield have enjoyed success."
O'Shea joins Joe Riley as a loan addition, whilst earlier this month it was confirmed Ethan Ebanks-Landell will remain at the Lane for the remainder of the season. In a busy transfer window, the Blades have also bolstered the squad significantly with the permanent captures of Samir Carruthers and Daniel Lafferty.
Speaking ahead of the O'Shea signing, the Blades boss explains why he was interested in securing the player's services.
