Eden Hazard has advised Chelsea teammate Kevin de Bruyne to leave the club.
De Bruyne has made just three starts under José Mourinho this season and is yet to complete 90 minutes for the Blues.
Belgium forward Hazard, who is international teammates with De Bruyne, believes it "would be good" if De Bruyne left Stamford Bridge with the 2014 World Cup seven months away.
"For sure, playing at a World Cup without having been in action for a year, I think that's very difficult. I think for him that leaving and playing, that would be good," Hazard told Belgian public broadcaster VRT late on Sunday. "If we want to get the best out of Kevin, I think that it's best if he leaves."
Bought when Roberto di Matteo was Chelsea coach, De Bruyne joined from Genk for £6.7 million last year and was immediately loaned out to Werder Bremen.
He has made only made six appearances for Chelsea and disappointed on his last start in the Capital One Cup win at Arsenal.
Despite his lack of game-time in England, De Bruyne started in Belgium's three World Cup qualifiers this season but did not feature in the friendly defeat to Colombia on Friday.
