Media reports claim that Chelsea are keeping tabs on Nico Guillen, who currently plays as a midfielder for Sevilla. The move is still in the early stages, but interest appears to be growing. The transfer remains in progress, and with no other clubs involved, Chelsea look to be negotiating from a comfortable position. Chelsea's 26/27 record of 2.25 goals conceded per game shows they're missing balance in midfield. Someone like Nico Guillen could give them more structure and help them manage games. Sevilla have also been linked with Lucas Stassin and Felix Correia while Chelsea are reportedly monitoring JJ Gabriel, Louis Page and Sander Berge.
