Arsenal have announced the signing of defender Jakub Kiwior from Italian side Spezia.
The 22-year-old featured for Poland at the World Cup in Qatar and was in the stands at the Emirates Stadium on Sunday evening to watch his new side beat Manchester United.
Kiwior, who had a spell in Belgium with Anderlecht earlier in his career, moved to Serie A from MSK Zilina in August 2021, and made 43 appearances during his time with Spezia.
Arsenal said Kiwior, a left-sided central defender, had signed a long-term contract, with the fee reported to be in the region of €20 million.
Gunners boss Mikel Arteta told the club's website: "It's great that Jakub is joining us. He's a young versatile defender who has shown huge potential and qualities with Spezia in Serie A and also at international level with Poland.
"Jakub is a player who will give us strength and quality to our defensive unit. We welcome Jakub and his family to Arsenal and look forward to working with him."
Arsenal sporting director Edu added: "We're delighted to have completed the signing of Jakub Kiwior. He's a young talent who we've been monitoring for a while now."
Manchester City have signed 20-year-old midfielder Maximo Perrone from Argentinian club Velez Sarsfield.
The Premier League champions have announced the Argentina Under-20 international has signed a five-and-a-half-year contract.
The PA news agency understands City have agreed to pay a fee of around #8million for the player.
Perrone is currently playing at the South American Under-20 Championship in Colombia and will link up with his new club after the tournament ends.
He will train with Pep Guardiola's first-team squad for the remainder of the season but has been signed with an eye on the future and is not expected to be involved this term.
Perrone has made 33 appearances for Velez since his debut in March last year, scoring three goals.
Aston Villa have completed the signing of Colombia international Jhon Duran from Chicago Fire, the Premier League club have announced.
Villa agreed a reported £14.75million deal with the Major League Soccer franchise for the 19-year-old striker last week.
Duran scored eight goals in 22 MLS appearances for the Fire last season and has three international caps to his name.
He becomes manager Unai Emery's second signing of the January transfer window following the arrival of full-back Alex Moreno from Real Betis.
A club statement read: "Aston Villa is delighted to confirm Jhon Duran has completed a permanent transfer from Chicago Fire for an undisclosed fee."
Duran is hoping to make his mark at the club quickly. He told Villa TV: "I have all the desire in the world. Lots of desire to work hard, give everything to the team and win. I'm hoping I can play soon.
"I’m a player that plays with a lot of passion who is dedicated to the team and a player that really wants to win always.
"I know it’s the most important league in the world. It’s the best league in the world, and I have all the desire in the world to get on the pitch and score that first goal."
Meanwhile, Liverpool have recalled defender Rhys Williams from his loan spell at Blackpool as potential cover for any transfer activity.
With senior centre-back Virgil Van Dijk sidelined by a hamstring problem until the middle of next month the club are keen to ensure they are not left short of options.
Nat Phillips is currently fifth choice, behind Van Dijk, Ibrahima Konate, Joe Gomez and Joel Matip, and has made only five appearances this season but it is understood he is attracting interest ahead of the window closing having previously had loans at Stuttgart and Bournemouth.
As a result 21-year-old Williams has returned from Blackpool, where he made 17 appearances, to cover all eventualities.
Michael Beale has completed his first signing as Rangers manager by bringing in Todd Cantwell from Norwich.
Rangers say the 24-year-old has signed a "long-term deal".
The versatile attacking player made 129 appearances for Norwich, winning two Championship titles and playing in the Premier League.
Cantwell also helped Bournemouth win promotion to the Premier League during a loan spell last season and had a temporary stint at Fortuna Sittard in the Netherlands earlier in his career.
Cantwell told Rangers TV: "I am delighted and I feel very proud. This is obviously a massive football club and I am delighted to get going and to get started.
"This is a massive club and there is a massive responsibility when you sign for Rangers to be the player that the fans want to see.
"They want to see a player that works hard and a player that can win them games which is very important and that is something I am hoping I can bring."
