According to CaughtOffside, both Premier League clubs are monitoring the 22-year-old alongside Manchester City and Paris Saint-Germain, although no formal bids have been made. Costa joined Porto from Juventus in 2025 and made 47 appearances with eight assists in his first season.

Porto have Costa under contract until 2030, with a €65m (£55.6m) release clause. The Portuguese club are therefore in a strong negotiating position should interest develop into a formal approach.

United could view Costa as competition at right-back, while Arsenal are attracted by his versatility and ability to contribute in possession. His strong start to the season has further increased attention around the defender.

Erling Haaland does not intend to remain at Manchester City if the club are relegated from the Premier League, with Arsenal among the sides linked with a move.

According to Football365, Arsenal have made contact with Haaland’s camp as they assess their striker options for 2027. However, reports elsewhere have claimed the Gunners have not made an approach.

City are said to have been found guilty of 114 financial-rule breaches, with the club expected to appeal once their punishment is confirmed. A severe points deduction or relegation has been discussed, although no final sanction has been announced.

Haaland is under contract until 2034 and has no relegation release clause, meaning any departure would still require a significant fee for City.

Barcelona are said to be keeping tabs on Estevao as he struggles for minutes under Xabi Alonso.

The young Brazilian has managed just 23 minutes on the pitch across Chelsea’s first five Premier League matches, with the Spanish press reporting Barcelona are prepared to take advantage of his situation.

Per the newspaper Sport, they are closely monitoring developments in his situation.

Arsenal have sent scouts to keep an eye on Porto’s Alberto Costa, per reports from Caught Offside.

They join a number of clubs, including Manchester United, in scouting the 22-year-old, signed from Juventus for €15m (£12.8m) last year. His contract contains a €65m (£55.7m) release clause.

Arsenal’s interest, though, is at a very nascent stage, which has not progressed beyond scouting. Meanwhile, the player, tipped as a replacement for Riccardo Calafiori, is playing regularly for Porto.

Manchester United have reportedly identified their replacement for JJ Gabriel.

The Red Devils are fighting to keep hold of their 15-year-old sensation, who rocked the club earlier this week when he requested to leave Old Trafford with immediate effect, just days before he was likely to make his senior debut in the Carabao Cup.

Though United still want to retain the services of Gabriel, they could struggle as he has interest from a host of clubs across Europe, including Real Madrid.

According to The Sun, they are looking at Lens teenager Mezian Mesloub as a possible replacement.

Manchester United have continued to bolster their academy ranks with the signing of Isaac Konde.

The 16-year-old winger has penned an initial scholarship deal at Old Trafford after leaving rivals Liverpool, where he had played since Under-9s level and who will be due compensation.

It was reported last week that Konde had agreed pre-contract terms with United on a five-year professional deal that will become active when he turns 17.

He is the third new signing at youth level for United in the last few days, following the arrivals of midfielders Karim Cassim and David Eze from Manchester City.

Arsenal and Tottenham could battle it out for the signing of Ibrahim Maza.

The 20-year-old attacking midfielder is shining for both Bayer Leverkusen and Algeria, attracting admiring glances from the Premier League.

According to TEAMtalk, Arsenal and Spurs have both stepped up their respective interest in Maza after scouting the player this season and assessing the feasibility of a move.

Chelsea, Manchester City and Aston Villa are also said to be watching his progress closely.

Chelsea may face a battle to keep hold of Estevao.

The Brazilian sensation has played only a bit-part role at Stamford Bridge so far under new boss Xabi Alonso, with his only starts this season coming in the Carabao Cup.

There have been several reports of Estevao’s growing frustration with his lack of playing time at Chelsea, with Barcelona now said to be keeping a very close eye on the situation.

Could we see Trent Alexander-Arnold make a sensational return to Liverpool?

It was only last summer that Trent departed Anfield for Real Madrid in a high-profile free transfer, which notably soured his reputation among some Reds fans.

However, TEAMtalk are now reporting that Liverpool are among the clubs interested in Alexander-Arnold, who faces a fierce battle for starts under Jose Mourinho at Real Madrid.

Arsenal, Chelsea and Manchester City are also said to be keen on the 27-year-old, who is said to be focused on Madrid for now and not considering a January exit from the Bernabeu.

Chelsea are reportedly among the clubs keen on signing Crystal Palace left-back Tyrick Mitchell.

Mitchell has started the new Premier League season in good form and scored twice for the Eagles in their 3-2 win over Fulham last month.

According to CaughtOffside, Chelsea see the 27-year-old as a cost-effective addition in defence, with Palace said to be seeking around £25m for a player who has entered the final 12 months of his contract at Selhurst Park.

Manchester United and Liverpool are also said to want Mitchell.
