According to reports in Spain, particularly in Andalusia, Chelsea are closely tracking the young Sevilla player Nico Guillen after he made his senior debut on the opening day of the LaLiga season. It is reported that Guillen has a €20m release clause, and he is a Spain U19 international.

It is reported that Chelsea's ownership group, BlueCo, is monitoring 18-year-old Spanish Sevilla midfielder Nico Guillén for a potential future transfer. Sevilla's sporting director, José Ignacio Navarro, has confirmed that no formal offer has arrived for the player, who recently received a new contract with an increased release clause. Guillén has had some first-team experience this season, and it is believed that Chelsea are not the only club tracking his progress.
