Former MK Dons midfielder Keith Andrews is to take up a full-time coaching role with the club this season.
Midfielder Gary Deegan has signed a new one-year deal at Southend.
Liverpool manager Brendan Rodgers' hopes of being able to bolster his squad this month appear to have been boosted after the father of reported target Yevhen Konoplyanka claimed there was substance to the speculation.
He said he was targeting a major signing and Dnipro Dnipropetrovsk's Ukraine international Konoplyanka, valued at around £16million, would fit into that bracket.
The player's father Oleg increased speculation about a move to Anfield by telling Ukrainian media outlet Tribuna: "I do not want to say specifically but the information about a transfer to the English club is true.
"He can change clubs later this week. We do not consider offers from Ukraine."
Having missed out on long-term target Mohamed Salah after the Egypt international instead opted for Chelsea, Rodgers is keen to make an addition before Friday's deadline.
There has been growing discontent among fans that no progress was being made to strengthen a squad which is severely depleted by injuries despite being in a battle to secure a top-four finish.
"I think we will hopefully do something over the next couple of days," said Rodgers after beating Everton.
"Hopefully we can have a major signing before the window shuts and if we can do that we will be set up for the remaining games."
