Manchester United have expanded their list of defensive options for the upcoming January transfer window by adding Brentford center back Nathan Collins to their shortlist. This development was reported by The Daily Mail and signals the club's intent to strengthen their back line. The Republic of Ireland international currently holds a contract with Brentford that runs until 2029. Given that Brentford currently sit in eighth place in the Premier League, they are expected to demand a substantial fee before agreeing to release the defender.

United's defensive record this season has drawn attention, as they have conceded 19 goals. Only Crystal Palace and Ipswich Town have allowed more Premier League goals this term. In addition to Collins, Fulham defender Calvin Bassey is also reported to be on the club's list of potential targets to improve defensive solidity.

Meanwhile, Bayern Munich remain actively engaged in talks to sign Liverpool teenage winger Rio Ngumoha. According to Bild reporter Christian Falk, the Bavarian giants are still interested in the 18-year-old despite previous moves in the transfer market. During the summer, Bayern were prepared to pay 70 million euros to secure the left winger, aiming to complement Luis Diaz. However, they ultimately signed Ismael Saibari instead.

The need for a left winger persists for Bayern, and they could attempt to sign the England international in either the January window or the summer. Their continued interest suggests they view Ngumoha as a key long-term asset for the squad.

Arsenal are also active in the market, with reports from TalkSPORT indicating they are eyeing a January move for Real Madrid forward Endrick. The 20-year-old Brazil international has seen limited action this season, with just 114 minutes played. Arsenal are seeking attacking reinforcement on the wing following the injury to Bukayo Saka. Endrick is one of several options being offered to Premier League clubs, though competition is expected from AS Roma and Sporting CP, both of whom reportedly want to take him on loan.

Further reports from The Independent suggest Arsenal are also monitoring other wingers, including Atletico Madrid's Alex Baena, RB Leipzig's Antonio Nusa, and AFC Bournemouth's Junior Kroupi. The club may use funds from a potential departure to sign a wide man, with Real Madrid, Atletico, and Chelsea all interested in central midfielder Martin Zubimendi.

AC Milan are making early moves for Club Brugge striker Nicolò Tresoldi, with plans to pair him with Gonçalo Ramos. Gazzetta dello Sport reports that negotiations will be costly, as Brugge rejected a 35 million euro bid from Roma in the summer. Tresoldi has scored 13 goals in 15 games across domestic and European competitions this season, and a fee of 50 million euros is now expected to secure the 22-year-old.

Other notable rumors include Liverpool potentially allowing Jeremie Frimpong to leave amid interest from Al Hilal, and Crystal Palace resisting bids for Chris Richards from Internazionale. Bayer Leverkusen are showing interest in Borussia Mönchengladbach's Wael Mohya, while seven clubs have shown interest in Dinamo Zagreb striker Dion Beljo. Juventus have inquired about Gianluca Scamacca, and Internazionale may sign a center back if John Stones' injury issues continue. Stuttgart is open to selling Bilal El Khannouss for 40 million euros, with Galatasaray monitoring the situation.

Newcastle United would need to pay 30 million pounds to sign Middlesbrough striker Will Lankshear, while Aston Villa are interested in Galatasaray midfielder Gabriel Sara. Napoli are monitoring several players including Alessio Cacciamani, Patrick Zabi, and Tylel Tati. Crystal Palace are leading the race for FC Salzburg's Bartosz Mazurek, though they face competition from several European clubs. Fiorentina are watching Cagliari goalkeeper Elia Caprile, and Eintracht Frankfurt are interested in Nottingham Forest's Arnaud Kalimuendo, with Forest demanding a 30 million euro fee for a permanent deal. Edon Zhegrova may leave Juventus in January for more game time, and Nuremberg goalkeeper Jan Kuchert is a candidate to replace Finn Dahmen at Augsburg.
