Sheffield United boss Chris Wilder is confident the club is close to extending Dean Henderson's loan deal from Manchester United until the end of the season.
The 23-year-old has been outstanding for the Blades as they have mounted a surprise challenge for European football during their first season back in the Premier League.
Henderson's loan is due to expire on 30 June, with any extension for him to remain at Bramall Lane for the rest of the 2019-20 campaign, which now ends on July 26, needing to be finalised by Tuesday.
Wilder has spoken to Red Devils boss Ole Gunnar Solskjaer about prolonging his stay to cover the extended season.
"I believe it's now just administration with the two clubs," said Wilder. "I had a chat with Ole and he was fine with extending his loan until the end of the season.
"Hopefully, that will get signed off before the deadline. I appreciate Ole's help on that one. Dean has been great for us and we have been great for Dean."
Wilder has previously stated that he would been keen to have Henderson back at Bramall Lane for a third loan spell next season, having also had the goalkeeper during last season's promotion-winning campaign, although he has accepted that the decision is not his.
Under the terms of his loan, Henderson is ineligible to play against his parent club when the Blades travel to Old Trafford on Wednesday evening.
Wilder will have to make another enforced change at Old Trafford, with Republic of Ireland defender John Egan suspended following his red card in the defeat at Newcastle.
Meanwhile, Tottenham defender Jan Vertonghen and goalkeeper Michel Vorm (36) have both agreed to extend their contracts until the end of the season.
Belgium international Vertonghen was due to leave the club on 30 June but has signed a temporary deal until the current campaign is finished.
The 33-year-old, who joined Spurs in 2012, is still expected to leave the club in the summer, after reportedly holding talks with a number of European clubs.
