Chelsea are watching Valencia striker Paco Alcacer.
The youngster is Spain's new striking star, having resisted interest from Liverpool and Arsenal as a junior to make his career with Los Che.
The Sun says Chelsea sent scouts to watch Alcácer during Valencia's clash against Malaga.
The forward is also a member of Vicente del Bosque's Spain squad and regarded highly inside Spanish football.
Los Che will be reluctant sellers should Chelsea firm up their interest in January.
