Middlesbrough 2025 summer transfers: Every confirmed signing and sale

Middlesbrough Football Club are playing their 150th season in 2025-26, and what better way to mark it than with promotion back to the Premier League for the first time in nearly a decade; at least that is the target for new head coach Rob Edwards.

The former Luton Town boss took over from ex-Manchester United midfielder and coach Michael Carrick ahead of the campaign, and he made an encouraging start to his tenure with back-to-back league wins against Swansea City and Millwall.

In terms of their transfer business, Boro completed eight additions to their squad during the summer window, including the permanent arrivals of Alfie Jones, Callum Brittain, Abdoulaye Kante, Kaly Sene and Sontje Hansen.

They also secured the signature of centre-back Adilson Malanda, although he was loaned back to Charlotte FC until the end of the season.

Boro dipped into the loan market to bring in left-back Matt Targett and midfielder Sverre Nypan from Newcastle United and Manchester City, respectively.

Meanwhile, Middlesbrough sold Finn Azaz to fellow Championship side Southampton, while they successfully fended off interest in Hayden Hackney before deadline day.
