The transfer mill is churning once again, with Sheff Utd believed to be lining up a move for Frank Onyeka, the midfielder from Brentford. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. While Coventry, Birmingham and Valencia have shown interest, Sheff Utd currently lead the race - though the situation could evolve if a deal drags on. In season 25/26, Sheff Utd are conceding 1.5 goals per game (39 in 26 games), which points to a lack of control in midfield. Frank Onyeka would be expected to calm things down and protect the back line better. Alongside this, Brentford are said to be exploring Ruben Loftus-Cheek, Matteo Cancellieri and Kaye Iyowuna Furo with Sheff Utd likewise connected to Dan Neill and Ki-Jana Hoever.
