Chelsea are watching Bayer Leverkusen winger Karim Bellarabi.
The People says Bellarabi is on Chelsea's radar after the Blues spied on him during the midweek Champions League draw at Benfica.
The Germany international, 24, was watched by the London club during the stalemate as Jose Mourinho looks to improve his options out wide.
Bellarabi is renowned for his pace, a commodity in short supply at Stamford Bridge, and Mourinho is also tracking Leverkusen's Turkish playmaker Hakan Calhanoglu.
