According to Pete O’Rourke of Football Insider, Newcastle were one of the clubs looking at Kobbie Mainoo in the summer window, and their interest continues as they monitor his situation at Old Trafford. Manchester United blocked any potential move in the summer due to squad needs, and O'Rourke stated he cannot see United being willing to let Mainoo leave in the January transfer window. It is also reported that every club will be made aware that no deal is there to be made in January, even if Mainoo agitates to leave. Fabrizio Romano revealed that Mainoo’s camp fielded more than 10 and possibly as many as 15 enquiries from interested clubs in the latter days of the summer window. Part of the reason Mainoo sought a new challenge last month was a fear he will miss out on England’s 2026 World Cup campaign.

Man City are alongside Chelsea and Newcastle in pursuing Mainoo, according to TEAMtalk, which suggests that Newcastle have the strongest interest.

According to TEAMtalk, Newcastle are planning to make a move on Man Utd for Mainoo in the January transfer window. The outlet understands that manager Eddie Howe is a fan of Mainoo, and the club’s owners, Saudi Arabia’s Public Investment Fund (PIF), are willing to back him.

According to Team Talk, Newcastle United are particularly keen on signing Kobbie Mainoo, and manager Eddie Howe is an admirer of the player's abilities. The club is described as 'keen' and faces competition from other clubs. While the interest is strong, no bid or negotiations have been mentioned. Mainoo's market value is estimated at £70 million, with the January transfer window being a relevant period.

According to Transfermarkt, Newcastle United are monitoring Kobbie Mainoo's situation at Manchester United ahead of a potential January move. The report adds that Mainoo wanted to leave Manchester United on loan last month due to a lack of minutes and is not currently a starter under manager Ruben Amorim.

According to talkSPORT, Newcastle United are interested in signing Kobbie Mainoo, who is struggling for playing time at Manchester United under manager Ruben Amorim. The report adds that Newcastle manager Eddie Howe admires Mainoo and is prepared to make a move if the player's playing time does not improve.

According to talkSPORT, Newcastle United have joined the race for Kobbie Mainoo's signature and he is a January target for the club. Eddie Howe is eager to test Manchester United’s resolve with an official bid in January.

Journalist Jason Soutar revealed that Newcastle are interested in Manchester United midfielder Kobbie Mainoo and have inquired about the conditions of a potential deal with United. Soutar also mentioned that the United midfielder is open to the possibility of leaving Old Trafford. Mainoo has not participated in Manchester United's first two Premier League games of the 2025/26 season, against Arsenal and Fulham, which has fueled speculation about his future at the club. He is anticipated to make his first appearance in the Carabao Cup against Grimsby. Despite interest from several Premier League clubs, including Fulham, Crystal Palace, and Everton, Manchester United reportedly prefer to offer Mainoo a new contract rather than sell him. However, Mainoo has concerns about his role and future at the club, which might influence his decision on whether to remain or move.
