Chelsea's Champions League rivals Anderlecht have confirmed the Premiership champions are interested in their central defender Vincent Kompany.
Manchester United had also been linked with a move for Kompany
The 19-year-old was on Chelsea's wanted list in the summer but they ended up bolstering their left-back position by signing Asier del Horno instead.
"Chelsea are interested and maybe a deal can be done," said Anderlecht managing director Herman van Holsbeeck.
"I've advised Roman Abramovich to keep a special eye on him."
The Belgian international was not in Anderlecht's squad for Tuesday's opening Champions League clash at Stamford Bridge, which Chelsea won 1-0.
