Burton Albion have re-signed defender Sam Hughes from Premier League neighbours Leicester City, as well as making three deadline day loan swoops.
Jimmy Floyd Hasselbaink re-signed midfielder Harry Chapman from Championship side Blackburn Rovers.
He then succeeded with a late move for Bournemouth striker Christian Saydee for the rest of the season.
Manchester United's 21-year-old Czech keeper Matej Kovar then also completed a late loan move.
Kovar, who has also signed a new contract with United, has been at Old Trafford since 2018 and spent last season on loan at Swindon.
Hughes, 24, signed by the Foxes for a reported £125,000 fee from non-league Chester in 2017, was already back with Burton on his second loan spell.
