Liverpool bolstered their defence on transfer deadline day by signing Ben Davies on a permanent deal from Preston and Ozan Kabak on loan from Schalke until the end of the season.
Injuries to Virgil van Dijk, Joe Gomez and Joel Matip – also now out for the season – have left the Reds short of centre-back options, so much so that captain Jordan Henderson has been deployed there.
But Davies, 25, has put pen to paper on a "long-term contract" after signing for an initial fee the PA news agency understands is £500,000, plus add-ons, while Liverpool have paid £1million loan fee for Kabak.
It is believed the Premier League champions have the option to buy the 20-year-old, capped seven times by Turkey, for £18m at the end of the season.
Kabak, 20, completed the formalities of the switch in Germany and will travel to Merseyside this week. He arrives at Anfield after two years in the Bundesliga, where he represented Stuttgart before joining Schalke in July 2019.
While the transfer window for Premier League and EFL clubs shut at 11pm GMT, the PA news agency understands Southampton have submitted a deal sheet in order to complete the loan signing of Takumi Minamino.
Saints had been looking at a full-back on Monday but turned their attention to the attack before the deadline.

The move would free up Shane Long to join Bournemouth, who in turn seem resigned to losing forward Josh King to Everton.
Schalke, meanwhile, may have seen Kabak depart but they captured Shkodran Mustafi from Arsenal in a permanent transfer. The Bundesliga side say the 2014 World Cup winner has signed a deal until the end of the season.
West Brom have completed the deadline day loan signings of England international Ainsley Maitland-Niles from Arsenal and Turkey midfielder Okay Yokuslu from Celta Vigo.
The pair have moved to the Hawthorns for the rest of the season to aid the Baggies' battle against relegation from the Premier League, with the club 19th in the table ahead of Tuesday's trip to rock-bottom Sheffield United.
Glück auf and welcome to Schalke, Shkodran! ⚒️👋#S04

Fellow strugglers Fulham have strengthened their forward options in a bid to retain their top-flight spot, signing Bordeaux striker Josh Maja on a loan deal for the rest of the season.

Tottenham goalkeeper Paulo Gazzaniga joined Elche on loan for the rest of the season.
The Argentinian has not featured for Spurs this season, falling behind Joe Hart in the pecking order as understudy to number one and club captain Hugo Lloris.
Another keeper, Jonas Lossl, left Everton to return to Danish side Midtjylland, his first professional club.
The 32-year-old did not make a first-team appearance for Carlo Ancelotti's side following his move from Huddersfield in 2019.
