Maresca has nominated Rúben Dias and Erling Haaland as captains, but wants to add more players who can fill the role. Fernández, who has captained Chelsea, is one player the Italian has identified as a potential target. The transfer window closes on Tuesday night, and Manchester City are expected to make a move for the midfielder within the next four to five days.

The targeting of Fernández follows the departures of Rodri and Nico González, and another forward may be recruited given Omar Marmoush's expected move to Tottenham. Liverpool's Cody Gakpo is being monitored, and Jack Grealish, who is of interest to Sunderland as a loan, may also leave the club.
