Nigel Clough says he remains hopeful of seeing Chris O'Grady back in United colours soon, despite the striker being recalled by his parent club Brighton & Hove Albion earlier this week.
The 28-year-old impressed in his four Blades starts, scoring once in the draw with Walsall at Bramall Lane and Clough says discussions bettween the two clubs will continue, despite the Seagulls appointing Chris Hughton as Sami Hyypia's successor on Wednesday.
The Gaffer remarked: "Brighton said they needed to recall Chris and he would go in the squad straight away and he was, he came off the bench at Fulham on Monday night and claimed an assist for their second goal in a 2-0 win.
"But we are hopeful that despite Brighton appointing a new manager, they will allow Chris to re-join us at a later date, as they stated when we initially loaned him that they were willing to potentially let us have him until the end of the season.
"Sam Baldock has been carrying a knock and they were very honest with us when they recalled him."
Clough added: "But at the same time, Chris Hughton may decide he wants to see him play and get him involved, that's out of our control.
"We just hope for our sake that will be able to do a deal to getChris back at some point in January, but in the meantime we will look at other targets and see if we can get someone else in."
