Antonio Fernandez Casino has reportedly emerged as a transfer target for Chelsea, with the Premier League side said to be eyeing a move for the Barcelona midfielder. Speculation is gathering pace as the club looks to bolster its squad ahead of a crucial second half of the season. Dortmund, Manchester City and Paris SG may look to intervene if talks continue without resolution. So far this season, Chelsea are steady at both ends (1.62 goals scored per game, 1.14 goals conceded per game). The role for Antonio Fernandez Casino would be to keep that balance while lifting performances across the pitch. Barcelona continue to be linked with Mickey van de Ven, Alan Godoy and Joao Cancelo while Chelsea are also rumoured to be tracking Marcos Senesi, Ruben Neves and Charlie Cresswell.
