The transfer mill is churning once again, with Chelsea believed to be lining up a move for Martin Zubimendi, the midfielder from Arsenal. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. Real Madrid have not withdrawn their interest and could still influence the outcome. In season 26/27, Chelsea are conceding 2.5 goals per game (5 in 2 games), which points to a lack of control in midfield. Martin Zubimendi would be expected to calm things down and protect the back line better. Arsenal continue to be linked with Axel Donczew, Igor Paixao and Matias Fernandez while Chelsea are also rumoured to be tracking Francisco Fernandes Conceicao, Lamine Camara and Iliman Ndiaye.
