Media reports claim that Chelsea are keeping tabs on Milton Delgado, who currently plays as a midfielder for Boca Juniors. The move is still in the early stages, but interest appears to be growing. Talks remain ongoing, though with no rival clubs reported in the mix, Chelsea are progressing without added pressure. So far this season, Chelsea are steady at both ends (1.89 goals scored per game, 1.22 goals conceded per game). The role for Milton Delgado would be to keep that balance while lifting performances across the pitch. Reports suggest Chelsea are monitoring Rafael Leao, Min-jae Kim and Jeremy Monga whereas Boca Juniors have not been associated with other players at this stage. More on this story as it develops.
